Historically speaking. ....yes they used to. Ive been buying k2s since 1988. And about every pair I had, which was alot, ended up with duck tape or epoxy on the tips because of delamination. And at the end of every season, everyone would send their K2s back under warranty. So K2 was sendind out tons of free skis every year.BUT, the first Public Enemy had the rivets in the tip and tails, which was about 2002 or 03 I think, and those virtually eliminated k2's delamination problem. I've continued to buy k2 about every year since and have not seen anymore delamination.
