MSPs are an awesome every day ski for the Midwest. And you def won't hate them on a pow day. They aren't super fattys or anything, but there's a reason they've been our best selling ski for 9 years now. Sterbenz rides those all the time in the park, and on the odd pow days.
As for edge durability, we've seen almost all our warranties disappear since we've moved construction over to Elan in Europe the last few years. They are super good at what they do over there.
