I've ordered a P85 from Curt but haven't had a chance to run it on my build yet (and haven't ran it with a cat clutch either to compare), but here is something to think about. My brother is the service manager at a dealership that use to sell cat and polaris and a few years ago they dropped cat and just do polaris now. Over the years he has been there (I think around 15yrs) he said he has seen LOTS of cat clutches break, and have you noticed that cat is always building a different clutch? Some years is a 3 tower, some are 4 tower, but they are always changing every few years, and he said he has seen MANY more failures on cat clutches over the years and very very few on the polaris ones (and I'm talking about major things like spider breakage). Polaris has had the same basic clutch for many many years, why? because it just works, so why change it? Being lighter weight probably won't give you extra power as a general rule because it is like a flywheel that is always spinning, what it WILL do is get the power from the motor, thru the belt to the track MUCH faster because the motor doesn't have to work nearly as hard to increase the rpm from say 2000 at idle up to 8000 wide open, because it has less weight to move, but once it's there, I think it is pretty much there. Just my opinion, but I'm sold on it without running one yet, and yes Curt is the perfect kind of guy you want on the customer service end.
