Look. they are good skis. but there is no way they will hold up that well out of the park. thier performance just isnt comparable to other twintips when its out of the park.
First of all, you HAVE to have them centermounted. which is a bitch cuz the center of balence is all janked up. basicly, your skiing no better if your headed straight in powder than you would if you were switch in powder, due to the symmetrical design and the centermountedness they have.
I personally dont like centermount even in the park. I ride rossi scratches, which are a much better all around ski. sort of like the line chronics and k2 public enemys. I have them mounted inbetween centermount and regular. they work flawlessly that way. they kill it outside the park, yet they still own it within the park.
If you are going to stick in the park all the time, get the invaders. otherwise, pick up a pair of Rossi Scratches, K2 Public Enemies or line Chronics.
