Where did you see / hear that? I've seen Centerforce Dual Friction clutches holding 400+ horsepower with no problems. My only complaint about the DF's is that they weren't SFI approved last time I checked.
To answer the question though:
The Centerforce I Clutch feels a lot like a stock clutch, but is has 30% more holding capacity than stock.
The Centerforce Dual Friction will not have a stock pedal feel, may be slightly more "jumpy" and has 90% more holding capacity than stock.
ACT Clutches are my prefered brand though. They are SFI approved an come in a variety of pressure plate & disc combinations to suite almost any driving style.

I also have a PDF document from ACT that will help you to choose the right pressure plate / disc combo. If you want it let me know, and I'll figure out how to get it to you.
