Joe,

I had the same problem on a car we built for a customer. Everything was fine till you got it over 6,000 rpm and then the clutch would stop working till the rpm came down. Swaped it for the 3 finger and no more problem.
Just thought it would help if I went in to a bit of detail about what is going on. The larger the pressure plate the faster the problem comes up.
I had the same problem on my 63 Corvair convertilbe when I was a kid. If I wound it up to high the clutch would act up. Took a bit of time and playing with other cars till I figured out what was going on.
Trial and error can teach you a lot. That and my very good friend Uncle Murphy is never that far away and always showing me new ways of having things go wrong!
