This may sound counterintuitive, but today I had my best carving day ever, and I think it's due in part to riding soft spring conditions over the last few weeks. Today was the first time on hero snow in probably four or five weeks and it was truly and epic day. Everything just worked.
I think riding in poor conditions (very soft snow, ice, crud, etc) can really improve your technique by showing you exactly where your weaknesses are.
Until I had a day in really soft snow, I didn't realize I was getting too much weight on the nose of the board. In softer snow I learned pretty quickly how to keep my weight centered.
So don't fret the next time you go out and the snow isn't wait you were hoping for. In the long run, it will pay off by teaching you better technique.
