I have a YFZ450 and I bought the 22x11x8 7 paddle haulers from Fullerton. Joe was very helpful and I would definately buy from them again. The paddle brats are supposed to rock too, a guy I know swares by them, but they are very exspensive in comparison and the comp cuts are prone to puncture if not careful (thin!!). If you use extremes, according to Skat Trak you should drop down one more paddle from what you would use on a hauler. Either way give Fullerton a call and ask for joe, he is way cool and very helpful. They ordered my paddles from Skat Trak for me and shipped them to me over night (for $15).
