i have a set of new beats both bottoms back then they cosindered these to be the rock setup cause there both very heavy they sound great no cracks. im lookin to upgrade to paiste dark energies so let me know if ur interesetd. i also have a 17 medium z custom no cracks, another 17 z custom with a crack but still sounds great just rattles here and there. a 18 meduim thin zildjian has a small crack in it. and if im very very up to it my 21 rock ride (all cymbals are treated with the brilliant finish very nice)
