Since i'm mostly intrested in the the f8's and what other peoples opinions are at this point in the season. mine is completely stock and runs very strong. the suspension is the best to date from arctic cat and with a little effort the handling is better then my f7 sp, i will be adding simmons skis this week to make it handle even better. i purchased the f8 lxr model for better trade value down the road. (hopefully) the speed and accelleration is right where i thought it would be. i can say at this point i'm very happy with the f8 and glad i did'nt spend the extra for the f1000. the top speed so far is 101mph with gps and that was'nt in good conditions.
