I got these picks particularly to be used for extreme metal. They have the classic tortex sound, all though the attack is sharper, compared to the regular tortex. This pick is pointier, and smaller overall. The pointier edge gives you more control and you need to use less power to play advanced passages. You simply have greater control.
From having tried quite a few picks recently, it is amazing how much the pick and strings do affect your sound. If you're into metal, this one is definitely worth a try.
