Here is how I see it, yes ON3P is more expensive than other ski brands. But the higher durability is worth it if you want a pair of skis that is going to last a longer time.
The skis I ride the most are my Jeffrey's and they have taken the least damage of any other skis I have owned. I ski over rocks repeatedly, ski through the parking lot, land on rocks, sidestep on rocks, they probably have at least 100 days on them of hard riding on them. Sure they have taken a couple core shots here and there, but there have been far more times that I have inspected them after hitting big sharks to not find any damage. The majority of my skiing involves uncertain terrain where you are certain to hit rocks hard and fast.
Sure, no ski is indestructible and some of it may be due to luck, but I have torn out edges, had core shots the size of my hand, and delaminated lower quality skis, and have seen my friends do the same on their K2 and Armada skis. I'm sure that K2 and Armada have some models that are more durable than their other models, but I think ON3P really exemplifies a dedication to quality, durability, and attention to detail across their entire lineup. To be fair I have seen a few cases of minor edge tearout and delaminations on ON3Ps, but it seems a lot more rare.
Yeah I'm a big ON3P fanboy, but it is cheaper to buy a more durable ski in the long run if you do a lot of skiing in unforgiving terrain
