I like the glides. it is likely just UHMW(PE). On carpet it will wear approximately 1/4" per hour of drive time. it may also get metal shavings imbedded and such imbedded in it from being moved around in the pit -- this will cause friction issues. I've considered the same but have not implemented to date. One nice thing about a static glide is that it will not get wrapped up in a deflated tube on the field like a caser will.
