Thanks Gregory; and yes, in the past I've asked about other strings and about B strings in particular.
I'm still playing TI Jazz Rounds, except for the B. I did a lot of reading, and a lot of comparing of string tension numbers, and eventually decided that nothing comes close to JR's.
For the past year or so, I've been playing with an Alembic E string tuned down to a D; so my tuning is D-E-A-D-G-C. I never use the lowest string in chords, it's just too far of a stretch from the lowest string to the highest string; so the lowest string is only used for open bass notes, and I don't care for an open low B.
I do however find the open low D very useful; and because I use a partial capo, the same string becomes an open low F when capoed at the 3rd fret. The other unexpected benefit is that the change in tension helped balance out the overall neck so that the C strings sits a little better with less tendency towards buzzing at the 13th fret.
I do wonder every once in a while about flats; the idea being that flats would eliminate finger noise. However, I'm guessing I wouldn't be able to get the tone that I'm getting with my current strings, an immediate example of which is the recording linked in this thread. And I'm guessing I wouldn't be able to manipulate the strings as easily as I can with these strings.
So to address the problem of finger noise I'll probably just have to keep working on technique. Might not get there in this lifetime, but perhaps in the next one.
