I plan on getting the Evo Stage 1 here soon. Should I stick with Evo’s clutch kit or would OSP clutch kit be better and why?

We ride northern Michigan trails at blazing speeds. Yesterday we were constantly hitting 75mph chasing down the dirt bikes. I overheated my belt and it started slipping at 60mph and had to drop down to 30mph to cool down with the stock bighorns. Given that information, what’s best for me? Thanks..
