Centerforce DFX or McLeod RST/RXT

[Vegas69]

As the snowball tumbles down Mt. Everest (Where is the gun to my head smilie) My current Centerforce dual friction isn't going to cut the cheese. Since I don't enjoy tearing my car apart any more than I have to, who is running a DFX? I've heard they chatter frequently? I can actually reuse the pressure plate from the DF and the DFX clutch is only $275. It's rated to 650ftlbs.
Going to the McLeod twin disc is more than likely what I'll do but it's 2.5-3 times the money. The RST is rated at 800ftlbs and is organic and should be quiet and have nice feel. The RXT is supposed to have similar manners but has ceramic plates and is good to 1000ftlbs. It's supposed to be more durable in a race enviroment. There is only $200 seperating them. Who is using these and do you like them?
Any other options I should consider?

I ran CF in my old car and they chattered and just did not stand up to abuse or power. (went through 3 of them) I'd definately recommend the Mcleod Twin-Disc.
