Oh man. Breckenridge's powder is light when it happens You'll be fine. That and the likelyhood of a large storm isn't that great. 10 inches of fluffy stuff isn't hard to ski in regardless of the ski you are using. Sure if you go to a windpacked area you may be a little bothered, but if you really can't deal, you can demo.
I think all of last winter (in Summit during one of their biggest years on record) I only took out powder skis maybe 10 times... and I skied many many days.
