I've had my AR7's for 8 months now, I ski on them 3 times a week in a snowdome so I've hit a lot of rails and jumps on them and the damage I've done to them is nothing more than cosmetic. I ski them pretty hard and I ski them in the park all the time.
The most major damage I've done:
Chip in the tip - put some epoxy in the chip which fixed it.
A smallish gouge/scrape in the base (I disastered a down flat but caught the kink with one ski) just put a bit of p-tex in it and fixed it.
Other than those the only other damage is minor top sheet chips and base scrapes from rails. But the edges and still crack free and strong and the ski still skis excellently and has excellent pop and everything.
I like to ski with loose underpants or boxers on so my balls can swish around and chill.
