When I can find them, I'm using Pyramid Maximum Performance 9-46 on everything but Strats and PRS with vintage-style tremolos. On those, I use 9-42, otherwise, they just don't feel right to me.
When I can't find them, I used Gibson Les Paul Signature, 9-46, or GHS Nickel Rockers, 9-42.
I used Thomastik-Infeld Plectrum for acoustics, 10s on my 12-string, 12s on my 6-strings for recording. I use Pyramid Premium Bronze Wound on my 6-strings, if I'm going to play out with them.
For my bass, Rotosound Jazz Monel Flatwounds, 45-130 (5-string).
