My friend just got a pair of Skogen's, and they ride nicely all over the mountain he says. But, since you are in Boulder, it seems like you would want the MSP's added width underfoot. A little better flotation on powder days. Both rip in the park I hear, so I am thinking the MSP's might suit you better in this case.
