After trying virtually every string out there, I tried the Thomastiks when they became available here in Nashville. I knew a lot of violin and upright players that swore by them. I thought it was a bit different that they only offered sets in one guage only. I must admit I was stunned at how good they were, especially running a 118 for my low B. The feel was terrific, and like Michael, I found they were 'bassy' sounding. As I play fingerstyle or with a pick, a thumb sound wasn't necessary for me. I was about to try some ALEMBIC strings, but when MARS was no longer an ALEMBIC dealer, I could no longer find any in Nashville. Plus I have this image in the back of my mind of the Austrians sitting around at the office . . 'but you vill only need one guage!'
By the way, Thomastik's website opens with a tribute to the late Ray Brown, which I thought was a classy move.
