Anyone use a SPEC clutch?

I love my SPEC I can't enough good things about it, just get one if you need a new clutch you won't regret it. I put mine in with the Tremec and my break in was 3 speed shift passes right off the lift. I did not ever have a chatter or maybe b/c I was not expecting it. I did however stall several times b/c the mofo grabbed so hard everytime I let off the clutch. :D This went on for about a week until I got used to it.
