So recently I discovered the joy of flatwounds, and decided to stick to them. I got a pack of GHS Precision Flatwounds and immediately loved the sound and the feel. I thought about not changing them for a very long time. But suddenly yesterday during rehearsal, after only 7 months of use, the A string broke while playing with the thumb. I now must replace the strings and have some questions. I actually felt that the strings were a bit fragile for some time, as if their surface was slightly "peeling". I'm inclined to think that they were not as solid as I thought. I'd like your opinion on which flatwounds you prefer in terms of durability. I usually prefer medium to heavy gauge, and the sound I play with my jazzbass style instrument is with both pickups on maximum and tone knob on zero. I can try pressure wounds instead of flats if someone gives me a very good reason. Long question short: I want to buy a flatwound that will last for a very long time, since GHS lasted less than I expected. Which one should it be?
