Personally, I would not use either of these boards at the ski resort.
70-80% kiting, get the Twisted, then buy a cheap board off E-bay for the mountain, and as your rock board for early season snowkiting. or maybe just rent when going to the resorts.
Here is a couple of threads that may answer some questions. Most of us are not going to use the new board as a rock board, and are keeping it aside until there is more snow.
A great description of the board is on the bottom of the home page at www.kiteutah.com.
As I have stated, I own the board but I have not tried it yet. However, the riders that have are very experienced riders and they all tell me it is the bomb. I can't wait to try it. Maybe next week as we have a big storm coming in this weekend!
