Both are great boards, but between the two, I'd go for the Raygun. It's a solid deck, especially for the price you're paying. I sold a couple to customers last year, and most of them came back into the shop raving about how much fun the board was for them.
The only issue I would worry about would be K2's Flatline base technology, especially if the conditions are super icy. The Magnetraction on the CC would help you out there.
Either board will suit you fine. Check out the Capita NAS for other board models to look at.
