So I'm looking to buy a new sled. I used to be heavy into riding but got too busy for about 10 years. I'm looking for some information on what kind of polaris to get. My main intention will be for ditch riding. I don't go into the mountains yet but would like to eventually. I really like the rmk's. The issue I have with them is that It's hard to find any without 2.5+ lug lengths and been looking at 144s or 153s. Now there are the assaults which I like aswell but don't really know the differences between them and the rmks but the lug lengths are way shorter it seems. What would the ideal lug length be for my intended use and track length? Also any sled recommendations?
