DR strings kick butt. I tried em out for the hell of it and I love it. I so much rather fit a set of DR's than D'Addario's though D'Addarios really are excellent strings. I used them exclusively until I discovered DR.
i used to have them in my Ibanez RG, switched to the DR coated series now. DR's version lasts longer, there was once i didn't change strings for 11 weeks. the black diamind version simply flakes off too easily. check if other stores have the black version because Davis now brings in only the red & blue versions.
