It’s possible that if your REM adjustment was done using the NL2 as the target, that will make the REM adjusted VAC+ result sound much closer than NL2. But if you didn’t have REM done on your VAC+ program, then it should sound more different.
For what it’s worth, I don’t have any REM adjusted program and I ended up keeping only VAC+ and DSL v5 Adult. NAL-NL2 is a little sharper than VAC+, but I found DSL v5 to give me the sharpest difference, so I removed NL2 and kept DSL.
@Volusiano: Yes, I remember you saying that. My own experience is driving me in the same direction.
[BTW: How did you like the pic of your Guru’sTemple®️?]
Haha, thanks for the pic! It should probably be reserved to the true masters here like Neville or Um_bongo though. They are the true masters of the trade. I’m just a user who gains some insights to the Oticon HAs thanks to being a DIY programmer of my own HAs.
Well, your insights are very helpful to me.
[You can keep the tent @Volusiano : we’ll get fancier yurts for @Neville and @Um_bongo]
Here’s a quick summary of what has transpired aboard Curly and Larry Mo’e, my trusty HearingEngines.
The Music program tweaks suggested by @Volusiano and @Neville were implemented, to great positive effect;
DSL-v5.0a was briefly tried and tested with a variety of low amplitude, high-pitched scratching noises. I thought my NAL-NL2 rendered them better to my ears, so NAL-NL2 was re-installed and its proper targets reset. I did not end up installing DSL v 5.0a.
The Telecoil program has proven to be very helpful to me, especially when taking calls in very noisy environments, so it was kept.
VAC+ remains my “go to / default” program. I was able to discuss the target values used with my audiologist’s REM setup - he explained the latest training he had received from Oticon regarding appropriate target values (basically slightly modified NL2 values), and how he was satisfied that the approach he used was necessary to adjust for the difference between my L and R ears. He was aware that the two rationales could be made to converge, but explained that he had consciously tried to preserve the distinct characteristics of VAC+ and NAL-NL2 as they are installed on my machines.
The Oticon startup jingle was replaced with a robotic voice that says “SpudGunner, start your engines!” 
[Just funnin’!]
Next appointment is in 3 months … my closing remark is an echo of Chuck @cvkemp: my default Oticon program eliminates the chore of program switching, and - although it’s not perfect - is reliable and so far has not let me down. Still, I will keep searching for ways to improve upon my understanding of the spoken word.
[I’m just a noob at all this HA stuff, and I’m extremely grateful to all the Members of this Forum that have taken the time to answer my many questions and have expended no small effort to set right my errant paths. Thank you!]
28 days and counting until I find out what my Audi has in mind for me.
@cvkemp: She may recommend a small dollop of “Tar” on your left ear mould to help it from working loose!
I have developed a better understanding of the different fitting rationales, and how my hearing mechanism responds to them …
The type of compression I need depends on whether I’m prioritizing audibility or speech intelligibility at the time. (For example, when I’m alone with the dogs and cats, some of which are advanced in age and who suffer various infirmities, I want just to hear if someone is sick or in distress. When MrsSpudGunner is in the building, speech intelligibility is clearly my survival goal!)
I can tolerate more gain across the board when there’s compression, allowing me to hear more soft sounds. This greater acuity, however, comes at the expense of the “crispness” of certain consonants, and with that, greater potential for misunderstanding.
Even though I have found great usefulness in being able to switch between VAC+ and NAL-NS2, I could easily live without the latter. VAC+ has given me a life-changing impact on my hearing, right out of the box, pretty well - it’s my GO pack/desert island program - and my More3s &VAC+ combo hasn’t let me down yet.
The type of frequency lowering and compression used by a rationale profoundly affects its suitability for musical situations. Even though Oticon’s protocols give me a pleasant perception of music, their “stock” music program did not do it for me, largely due to the presence of default values that were not suitable. If you’re a musician, achieving a useable Music program may prove as challenging as addressing speech in noise. My advice is to be persistent in checking out the default values inserted by Oticon.
Another thing that I have discovered is that my hearing changes through the day, and even though VAC+ may have worked for me all day, come 21:00h, I may need the extra “crispness” of NAL-NL2 to hear HerSelf®️when she summons me to do chores.
It’s nice to have that choice programmed right into your hearing engines, and that realization was, I suppose was the desired outcome of the comparison exercise.
I’m grateful to the members who’ve expended the effort to educate me! A sincere thank you!
@Volusiano: I realize that my More3s don’t have the Clear Dynamics feature that accommodates 113dB input transients.
Q: do you know how many dB they’ll handle before they max out?
I’m guessing that this question was derived from my comment in the OPN 3 review post with @e1405?
Below is the link to the Oticon Clear Dynamics whitepaper. While I can’t find where Oticon explicitly say what the input dynamic range of the OPN 3/OPN S3/More 3 is, I’m guessing that it’s at 90-95 dB roughly based on the 2 screenshots below from this whitepaper.
@Volusiano: Yes, that’s what spawned the question. I decided to ask it in my evaluation thread (perhaps a mistake?)
Thanks for the link to the white paper. (But I saw no such diagrams in the link that I downloaded.)
@Volusiano: 113dB is a very loud transient for an acoustic guitar. In a recording studio, I’d be knocking that down right off the bat with a tiny bit of fast compression with a slower release time - even though I like to record dry and then add compression as required for the wet mixdown. (Well, I don’t add it - the engineer/producer does that …).
So, Clear Dynamics probably wouldn’t sound very pleasing to my ears.
[We should enlist @christiansleep to comment on the magnitude of these transients: he’s a very talented musician/recordist.]
Only if Genie2 ran on MAC OS!.. I am also a MAC only user and ended up buying this just to run Genie2.
this may have been a cheaper option, not sure to be honest, it doesn’t help much after you have already done it though
Just being honest, I am not sure what you are trying to ascertain, but from the bits I have read, as much dynamic input range as possible would be a good thing, because if you’re playing guitar and your hearing aid is compressing the input when it reaches a certain threshold, you are not getting a true representation of how loud you are playing etc.
I am not really sure without doing a bit more research how loud 113db is to be honest, can you let me know exactly what you are trying to find out and I’ll look into it for you
Thank you for the compliments on music, the irony of It being on a hard of hearing forum makes me laugh though just my sense of humour, @SpudGunner is also a very accomplished musician
Just giving a quick look, I have come across some of this stuff before, particularly the Fletcher Munson Curve, I am no techie with stuff like this, I am only para-phrasing what I have read elsewhere etc.
The curve basically states that sounds in the frequency range of 1-4k although being at the same Decibel level as the other frequencies. are perceived louder. (probably due to the fact that those frequencies hurt our ears more etc, (assuming that we can hear those frequencies), I work a bit with mixing music etc and I would call those ranges Hi Mid, there maybe different ranges used when describing (Bass, upper bass, low mid, mid, hi mid etc etc). It maybe a lot simpler like a hifi Bass, Middle and Treble for instance.
Anyway this link may help with what you are trying to find out
It has some good information.
Now as an example, although I haven’t worn my hearing aids since 2017, soon to change on the 27th when I will hopefully get new ones etc.
I have done gigs with the ones I have, when I gig I play amplified acoustic guitar, it was a lot brighter sound, due to the hearing aids being boosted from around 4k, which is where my Audiogram went Grand Canyon dipped back then, or they could have reduce the low end. I didn’t know as much as don now back then. The sound with them in wasn’t unpleasant just different I would say.
I hope some of that helps with what you are trying to find out buddy, if it doesn’t sorry for wasting your time and I know you’ll never get that time back

Well … thanks for all the work you’ve gone to, but it misses what I’m saying.
Here’s perhaps a better explanation of where I’m coming from:
I’m a finger style guitarist. 113dB is probably louder than the transients I generate with my fingers, so Clear Dynamics feature wouldn’t do me any good;
Even if I DID create 113dB transients with my fingers (unlikely) MY EARS would hear that as harsh and spikey - I’d probably just back off a bit with my playing;
But 1.and 2. (above) assume that 113dB will be a hard SPL for me to achieve with my fingers alone.
So - simply put - what I want to know is: how loud is a good acoustic guitar, when played with fingers alone? If it’s in the neighbourhood of 95dB or below, Clear Dynamics offers me no benefit.
[I take it from your answer that you don’t know the real SPL of an acoustic guitar when plucked with the fingers, and with the soundhole facing *away* from me. That’s what I need to ascertain whether the Clear Dynamics feature would be worth the extra $$$ for the More2.]
You might find this interesting. Sounds like you might hit 100dB but more likely will be under 90dB
Hi mate, this is my personal opinion. From a quick look around the internet etc as well.
I had already been reading up about dynamic range input, and despite manufacturers claims, it’s rarely as high as what is stated, at least from personal opinions on forums etc. People seem to think also from reading on forums Acoustic Guitar played normally to hard is in the 80-95 db range.
Obviously there are lots of variables how hard you play, design of the guitar, woods used, even down to the type of pics used etc.
How heavy handed you are, I have worn holes through guitars and when I first got my martin I had it re-fretted after a year.
135db is 700watt marshal head 4 x 12 on max from a few feet away.
Now 60-80DB average acoustic guitar playing, one guy tested two of his guitars and the max he could get was 95DB with an spl meter point at the sound whole from 2 feet away.
Does your acoustic ever sound harsh or like it’s compressing?
Would you have to pay the extra dollars yourself?
I would probably hit the guitar a lot harder than you, I am very heavy handed.
My thoughts though if you are getting up and near the 95DB of your aids, I would go for the headroom of the 113DB one, only because if you are near the input max, its going to distort, and digital distortion is not pleasant compared to how a reel to reel pleasantly saturates the sound and boosts harmonic content etc.
Got an eye migraine so I am struggling to see the screen at the moment, and I have to go out in five mins etc.
You can probably get an SPLMeter App for your iPhone and measure the lvl yourself, that’s probably what I would do to be sure x
had a quick scan, running late, will check it out when I get back from my covid jab
thanks for posting buddy
@MDB: 
LOL! I just found the same scholarly article! I was surprised that the classical guitar average SPL at 85dB topped the steel string level of 80dB.
It took quite a bit of good Googling to turn up this reference, and I thank you for taking the time to look it up.
It is as I suspected: these measurements, plus the fact that the soundhole of the guitar faces away from me as I play, pretty well negates the value of Clear Dynamics for me.
Thanks again!
++++++++++++++++++++++++++++++
@christiansleep: And thank you, as well, for your efforts on my behalf.
I would, indeed, have to pay for More2s out of my own pocket (which I frankly can’t afford). The expenditure wouldn’t be justifiable, based on what you and @MDB have turned up.
So … one less moot point, about which to worry!
