Found these 3 years ago, havent managed to get through the pack yet, they just dont wear down ! Great grip in them, they feel like they are made of stone ! I play Rock, blues, country and jazz with the same pick through out, I dont see the sense in using anything else. I found them invaluable in a studio setting as well. when you need everything working and you are under pressure, it is great to be able to rely on some things at least !
