Replying to Repairing Skis, what epoxy?

So about a week ago I fell in a race and delammed the fuck out of my GS skis. The topsheet is now separated from the core all the way from the tip to the front of the binding. Being a broke ass college student, I can't really afford to buy skis, so I'm gonna try to repair them since there isn't any structural damage. Have any of you guys done a repair like this before? What epoxy did you use and did the repair last long?

Also, if any of you who see this actually make skis, what tensile strength is the glue you use rated to?
