I was talking to a friend of mine who is the poo mechanic about long track 600s and he said the poo 600 155 was under powered. I think a 144 would be good though. that is what i will try for next winter.
I guess you do not see many 600cc sleds that have much more than a 144" track on them.
I would think that the Hawk is slightly more effecient in putting power to the snow with the belt drive and the narrower track might keep the track speed slightly higher than a regular sled.
Is there enough room to put a 2" paddler under there clearance wise? Didn't sotck come with a 1.5" right?
