Which one would you buy. I dont like the track on the assault. I have a 2010 Asault and ditched the track for a camo extreme and it rocks. I love the lenght of my current sled but I could put up with a 155. Whats different between the 2 other than shocks? What makes the assault 15lbs heavier? I know the track is heavier, but not all 15lbs. Are the rails beefier? A-arms? Any input is appreciated.
