If you want durability, just get the ON3Ps. Seriously. Nothing else comes close. They literally have the thickest edges and bases you can buy from a factory without getting into special order crazy custom made shit, which would just be silly. There is no other competitive product in terms of durability IMO and I've skied a lot of indies.
The next closest is Probably Praxis but they don't use quite as thick of edges and bases iirc, so seriously, if you want a tough ski, just get an ON3P. You will never regret the decision, that much I can promise you.
