Used these for years, on various skis, since the old Ascension purple days. Always loved them in conditions downunder in Australia. Never needed long skins out the back.
Got a pair of 80mm new Glidelite Mohair Mix kickers and tore them pulling them off first season. Bugger, my bad, so coughed up for a new pair. The stainless plate sits off the base and catches in the snow and eventually the skin falls off. They also get very wet quickly, despite waxing. Seems like the shape of the plate has changed or the newer wider ones can't handle the forces involved, looks like the plate doesn't sit flush against the base to me.
Not great, will force me to use longer skins, which is a real shame down here. Much heavier.
