I'm a thomastik fan - I have TI JF344 on a jazz, three precisions & a thunderbird, JF324 on a mustang & a daisy rock, JF345 on a Peavey 5er, pluse a set of thomastik spirocore weich on the double bass.
Blummin' expensive if I ever have to replace any, but I have a spare set each of JF324 & JF344, so I should be OK for ten years or so.
