At first I have to point out that I`m no guru of any kind -But if I understood what you wrote about resonating adjacent strings with octaves correctly, are you talking about sympathetic resonance? It can be a problem with EB`s, EUB`s and amplified uprights, but for acoustic playing and intonation practise it is what I`m after in the first place. It`s about more audible tone and your instruments natural way of showing you the correct pitch. There are different takes about it for different players, and for different musical situations, but all in all, it`s the nature of a gigantic acoustic instrument
IMO and IME, comparing playability issues between EB`s / EUB`s and uprights just doesn`t make sense, it`s a different game with acoustic upright. The bass guitar frame of mind just doesn`t work out the way you wan`t it, stopped notes will sound very different in different spots on the fingerboard, and taking advantage of the open strings is a part of it all. I`d be more concerned about tone production, intonation and time-keeping than whatever fingering would work out for certain walking lines. With acoustic upright, as a BG player, you have the advantage of knowing about fingerboard, ie where the notes are, and knowing the music well allready. Playability will be different and have to be relearned anyway. -And sorry if i got you wrong, I didn`t read thru all the thread.
With all this said, nothing wrong with wanting a 5-stringer UB with low B. Those low notes can shake floors, and it`s highly addictive.
