I’m looking for a B string gauge that can function on a standard 34” scale 5 string that could also be tuned down a whole step to A without being too floppy. I like heavy strings so it being tight in standard isn’t too much of an issue for me. Any suggestions? I plan to use 50-105 or heavier for the others. On my current bass I think my B is a 130 but it feels very floppy even in standard.
