I am currently using an esp wasp for my overstable mid and was toying around with the idea of changing this up. I never really liked the kc plastic but I am willing to give it another chance. Anyone have any input as far as the differences between the kc roc and a wasp? I'm guessing the wasp will be a little more stable. Also, anyone notice any differences between the 11x roc and the 12x roc?
