you need turf or first, but just use your normal wax. If speed is a problem, its not about wax, but about the drop-in or if the turf/carpet is broken in or not
Wax for the skis doesnt change, just use what ever. all you're doing is keeping the bases from drying out. Otherwise it doesnt help you slide any better as wax is there to create a melted layer of snow you can slide on (kinda basic way of putting it) It's more about the carpet and piping and keeping it well lubed
