As much as it might suck, I would strongly recomend doing the warrenty and here is why....
If you try and fix it yourself and you fuck up the skis even more, there is VERY little chance the manufature wil take it back after your hack them up. They will see that you tried to fix them and they will deny your request to get them replaced.
If you send them back now, they will be replaced.
Just my 2cents
