Replying to Ninthward Ski Question

Hello

So for $280 NZ I can pick up a brand new pair of Ninthward HHP skis from levelninesports.com.

I'm 170cm tall so I'll buy the 172cm ones. These skis will be used purely for park skiing (lots of rails and small/medium jumps) at an indoor slope so I don't care what they carve like or anything, pretty much the only thing I care about is that they're durable.

So are they a durable ski? Will they last me a while for quite a long time or will they break on me in like the first month of skiing?

Thanks for any help
