Just curious, but did you email us for a warranty? I cannot imagine we wouldn't replace a ski that delammed all the way to the tail (not sure exactly what that means, either, but I can't remember a ski ever delamming from the heal piece to the tail if that is what you meant here). Just figured I would ask.
As with any product, something shit happens. I would say, as a rule, ON3P makes far more durable skis than most of the stuff out there. Doesn't mean everyone has the same experience, but the vast majority do.
So far this year, we've warranty less than 5 pairs, total. Both the past two years, it was less than 10 pairs per year when all was said and done.
Hitting lots of rails is still going to cause damage to your edges. We do use a 2.5mm x 2.5mm edge, so it gives you longer life vs the standard edge thickness most everyone uses. That said, the wear and tear of hitting rails will have the same long term effect as with a standard edge. With the edges ON3P uses, it just takes longer to get there.
As for topsheet chipping, our edges are sharp and as with any ski built in a sandwich construction, sidewall chipping can be an issue. We hand bevel the topsheet in house and do a better job at it than most skis I've seen, but there is only so much we can do.
Periodically running over the edge of the topsheet with a file or a sanding black, especially when the skis have a bit of damage to them already, will help prevent the chipping from getting worse.
If you have any other durability questions, I am happy to answer them.
Thanks!
