considering the damn ski blew up on me after 6 or 7 days, i'd say don't count on them.
and by blew up, i mean my inside edge grabbed the rail, and tore out of the ski for about 100cm of the length of the ski without so much as a crack in it. along with pulling itself out, it pulled the entire core out...there were wood chips everywhere beside the rail...looked like a bomb had gone off from the inside of my ski...
get something else.
