I have been having problems from a health perspective which I have explored here: http://www.talkbass.com/forum/showthread.php?t=190275 Due to a project I am now involved with, I have gone from using fairly light gauge Nickel Round Wound strings to using Rotosound Heavy Gauge (50/75/95/110) Flats. Don't get me wrong - I'm more than happy with the sound (and "thump") that I'm getting from the Rotosounds BUT I'm now experiencing even more problems with my left hand and I've come to the conclusion that this could be due to the fact that my current string choice means that I'm having to cope with a much greater string tension than when I was using the light gauge roundwounds. So, my question really is twofold: 1. Is my assumtption correct? AND 2. Is there a flatwound heavy-ish gauge string I could go for which is specifically designed to be "low (or at least lower) tension"? Please bear in mind that: 1. I'm based in the UK. AND 2. I'm a starving bassist. Any help much appreciated as always.
