The Axys does trench more compared to the Pro Ride, I haven't had any negatives with a sittfer FTS though.
I find the sled lifts and goes foward thus leaves a trench behind, but i chalk that up to the light weight drive system that spools up really fast. Iv had a few people tell me that i leave trenches, i dont do it intensionaly, i chop the throttle alot when im in the trees, perhaps i need another technique lol.
