I believe it's all in how you're feeling in it. I personally like a pretty even balance (if that's possible) of chords, single notes, octaves and embellishments. At least that's what I strive for. Single note playing is probably a weaker point in my playing, but it gets better every year.
PS: I've got 13,992 views (since 2010) on a youtube vid, of me playing Cajun accordion... qualify for the bending note set up? Compared to 2416 hits of Dirk playing your bending note accordion (since 2008), I'd say you might have a better chance of getting interest here.
I could push your creation to the max, promoting it in any way possible. Once I'd get the hang of it, I could make multiple videos.
And I dang well would master it; I have not doubt. I've come a long way since I met you about a decade ago.
