I went to one of their stores to buy some heavy picks for my bass, and these were recommended to me, I gotta say I'm really impressed; these are the heaviest picks I've ever had in my life. They have a nice smooth grip so you wont drop it or have it slipping, it improves the way you play guitar or bass. It's expensive but it was completely worth it.
