I'm gonna hop on here. I've been riding a pair of last years 2012's, and they've been holding up really good. Can't say that this means that they're all durable, I might have just been lucky. I ride indoor alot, and have ridden probably close to 100 days on them. I've been hitting a lot of rails lately, but surprisingly no edge cracks yet, they seem to hold on really well, although i have dulled the edges really well. I must also say that I'm definetly not the hardest on rails, although i do hit DFD's and donkey dicks quite often.
Some topsheet chipping but not as much as i had expected. I do however have about 3 parts of edge dented in, of which one in the tip looks like a beginning delam, but has not gotten worse since about 3 months.
They have become a bit more flexible than they were at first though.
I'm just really stoked on this ski, and a friend of mine rides them aswell and also loves them.
Not saying there aren't other good options...
I've ridden chronics aswell which I really liked aswell.
