I like GHS boomers and I've kinda gotten into the likely "overpriced" EB cobalts.
But I seem to be in the minority in that I like 9's and I like standard tuning. I like the boomers on the hardtail ibby and I think I prefer the cobalts for whammy ibbys. In fact, the cobalts on my 3 whammo's have REALLY lasted. I'm not a god and don't really shred but I play enough to know the diff. Absolutely HATED the cobalts on my hardtail though.....they were too stiff, and too weird. Didn't tune properly.......totally the opposite of the two edge pros and the edge zero II
