The only pair of skis I currently own are (nearly) center mounted 178 Line Blends. I am 6' tall. I mostly just lap the park in the Midwest but under semi-often circumstances I'll find myself skiing pow, trees, and/or bumps. These circumstances are generally the one time a year I go out west, or when I go up to Mount Bohemia (which I'm planning to do soon). The last time I skied was a pow day at Granite Peak, Wisconsin, and in the trees I found myself having to take a lot of care to keep my tips up. I also went to Vail earlier and found them getting bounced around in moguls, though I only skied them for 1 day and demoed skis the other days. How much do these issues have to do with my skis in comparison to my own skiing skill?
I'm wondering if I should sell my Blends and buy a different ski as a one ski quiver. I'm thinking the Surface Outsiders, since I have heard really good things about them and they seem to be light enough and poppy enough for park in addition to a range of other conditions. Also they are very cheap for a new ski.
Should I get new skis or will my Blends be ok for progressing on off-piste and in the park?
