does anybody have one of these kits on there polaris. i have a prox 800 and
i was wondering which one would be better, and how many grams are the weights
that would be with the kit.

I dont think you could go wrong with both of them! I had a EPI pro kit in my xc 8 that really woke it up! I would expect 68~70 grams on the primary on both kits! my 2001 has 68 in it! it would run 7750 on a uncalibrated tack. think about gearing down just a little , I will pull even harder !

I'm thinking a prox8 would take 72g or 74g epi bellie buster weights. It seems like a lot of weight but I think it's how epi cuts their weights what makes the difference. Also goodwins makes a very good kit. Hope this helps.
