I've been playing guitar for about 12 years now, and I've always been using standard Fender picks. But after reading up on these ones, I decided to give them a try. And I've gotta say, I really am amazed by how much they affected my playing. They feel great to play with, they're the perfect size for me and they make shredding a piece of cake. The only (kind of) negative thing about these picks is that they are kind of slippery, but after a few days that issue was gone for me.
If you're a shredding guitarist I really recommend trying out these picks, they are simply amazing.
