I'm using DR DDT 12-60 to compensate for drop Bb (feels like using 10's in standard), and I am breaking one at the 4 week mark regularly. By 3 weeks they sound dead. I do play a lot, probably 10 solid hours a week, and I use .88 picks but man! I spend a lot of money on strings! I used to use ernie ball strings but I only only ever got 2 weeks out of those, max. For all you heavy hitters out there.. is this you? Or am I the hulk trying to work a smartphone here?
