What works good for clutching my F7 for the Black Hills, 03 snopro 1 3/8 track lots of studs 20/39 gearing. going this weekend looking for some ideas. thanks

63 or 65 gram weights are what i usually run but i have the aftermarket clutch kit and stuff... should run about there 63 are a little lite but they get in the rpm faster and you are a rocket out of the hole but the 65 you are perty steady all the way through... depends on what driving you are doing.... i like the 63 personally have'nt let me down.... you will have a blast in the meadows if there is good powder... the firecat is one of the better sleds for out there i beleive mine always seems to run better out there than back home on the flat lands...
