Good clutch for 450+ RWHP?

i've used my centerforce dual friction for over a year full of redline dumps on slicks & numerous other times on drag radials & i'm making 442rwhp. no problems what-so-ever.

from what i've seen on the net & people i know the centerforces do great until you start spinning them high, ie 7k
 
I had a CF DF on my old 96 GT and I have a Spec II on my 95 GT w/450 HP. I prefer the feel of the DF, pedal feel is so soft. The Spec II grabbed really quick, a little harder to slip. It was also notably stiffer.
