I just switched to a Dunlop from an Ernie Ball. The EB worked well, but when the string breaks you'll be up a creek without a paddle. PITA to fix, and I can't believe they haven't updated the design to use a better mechanism, or at least modified the casing for better access.
iahawk, out of curiousity, where were you hearing tone suck from the Dunlop? I feel that mine is good wide open, but can be darker when turned down, especially if I have an OD pedal engaged.
