What 10 1/2 street/strip clutch are you using?

I have a stout 420 hp367 cuber.I run a 3.55 on the street, or pretty much anything at one time or another. I've run a 4.30 at the track, this one time.
I've run the Zoom kit, and Now I have the CenterForce. I found the CFII disc too harsh for street, so now I run a Chrysler 340 organic disc. The CFII breaks stuff. I like the diaphragm; it's easy to modulate in traffic or parades, and barks the tires when I want it to..
