that sucks dude, i'd call/go see whoever you got the skis from, the shelf life has to be more than 2 yrs, unless you use them for javelin practice in the summer.
I emailed, they said they are out of warranty (>3yrs, but i didn't use them but once last year because of the injury). They suggested this was a 'compression' crack caused by going over a rolling hump while weighted, and that they are not uncommon. They said it is not a design or installation flaw (of course). I'm skiing my old 3pin gear now, but it's 30+ years old, and will surely break down soon. (see my log entry from jan 4!). I'll have to save up so i can buy a new pair. Maybe they'll have end of season sales....
