For all you guys with that have poor slide life, I just got 3500 miles out of my last set. They are cheap graphite slides, driven in all kinds of trails from early to late season riding. My nytro has no mods to the suspension. Only help it gets is a pair of snow catchers that bolt on to my simmons skis. Slides came from MFG Supply in Medford WI. I think the slides were less than $20 a pair.........
