I'm also interested in the Dupont slides after seeing a poster about them at my dealers. So far, they are only available for Yamaha, but I suspect they will come out with products for the other makes eventually. I used to just switch out hyfax once a year and never wore them out by the end of the season on my older sleds, but my XF seems to be harder on them. This fall I put on the Super slippery slides from HPE. If they are enough better to last the season, I will come out even on the cost as I paid $79 for a pair, and last year went through 2 sets of normal slides in just 1500 miles
