I don't know what's the best, but I know what sucks, for me anyhow.
ERNIE F'N BALL Strings. I bought a box of'em off Ebay a
couple of months ago, and restrung 3 or four of my gits with'em. Every
single guitar has popped the D String at least twice. I've never had
a problem with Ernie's before, but this batch sucks out loud. I'm a bit
of a flogger , but not so much where I have to wear safety googles when
I play, so I don't put an eye with strings busting all the time.
Before the ERNIE F'N BALL fiasco, I usually
use Dean Markley, and no D string time bombs in the whole time.
