I run the 1.75" Ripsaw Lite Single Ply track. So far it's great. I also installed extros (2.86" Pitch) and trimmed the rail tips. Haven't looked back. 2" would be nice occasionally in the really deep stuff (but that's what the REV is for), but this track is awesome on the trail and isn't too hard on hyfax. That being said- I think anyone with an XTX who is thinking about running a 1.75" and up track should probably consider a set of Hiperfax. I typically ride in good snow conditions, but went through three sets of stock hyfax last winter in 2500mi. Since the Hiperfax- not a single problem.
