I'm looking strong at an axys right now. I tried one 2 weeks ago for the first time, a 163 3". I can honestly say that it didn't hook up near as well as the 153 3" pc on my cat. Not sure what the Polaris track is like in bottomless but I wouldn't consider the powerclaw to be a trencher. Look at an XM if you want to see what real trenching is. If I make the swap to an axys there will be a 3" powerclaw on it before long.
