I am finally getting into a position where I can start looking at purchasing a snowmobile. I'm looking for a sled to take out ice fishing and still have some fun with the guys on some runs. A few that I have rode have been uncomfortable for me, I'm 6'5". They have been mainly rocket sleds. Is there any utility type sleds that would be comfortable and fast? Doesn't need to be a rocket, maybe in the 600-800cc range.
