Awe-in-one Thrash II's.
I ordered them when I was drunk on the internet and forgot about them until they arrived at my door.
I have to say that I was incredibly apprehensive about using it in a practical setting for my playing (brutal death metal), but I recorded a few riffs with it, and now it sits really well in my hand while I play.
Its really sick to play with. And the other edge makes squeals so easy.
10/10 would recommend. If you're looking to replace your picks or wanting something different from your last pick, give this a go.
I may try these... my Jazz III Max-Grips slip and move in my hand a lot when I'm doing death metal riffs with lots of trem picking. Cheers man!
