hi, i have been sledding for a couple of years and i am thinking of picking up a hawk. most of the ones i see around alberta are the '03 503f's. i ride in the mountains, are the 500's up to the challenge? or would i be better off waiting for a 600. also seen a bunch of stuff about needing an upgraded ski and some reference to a chaindrive rather than the belt. are these things a must have? how easy is it to pump the 500 up to around 100 horse? thanks
