I wax for Nordic a lot, and obviosly don't spend so much time on my alpine skis because they get beat up pretty bad. I'll use a soft wax and throw them in a hot box about once a week, and wax with a wax suited for the general temperature of the snow after that. I don't grind or use anything hi fluoro as I would with nordic skis. its just not worth it. I have found that the Swix f4 iron on works really well in most all conditions though.
Anyhow has anyone seen the new Fischer JibSkate? It's pretty sic. The first nordic twin tip.
