Fine, i have two pairs of JP's and my brother has a pair and they have held up great,,, mind you we arent hitting the rails all day everyday,,,we have park skis for that. But for the average use it should be OK.
Also i wouldnt go too much off that website thing mentioned above,,, itt is all marketing. the lizzies for example might be marketed as a park ski, but it really excels in pow. anythng with a waist like that is going to be great for pow.
I just wouldnt buy the JP thinking it is going to be mostly used in the park,,,,,unless mayby , mayby if you were considering the 178.
