You are an All-Mountain freerider. You stick to the groomed runs, trees, and powder when you can get it.
In that case, stay away from all pure rocker boards. Those are park boards. They'll be too soft, have less pop, and won't hold an edge as well as the hybrid or full camber shapes.
The Sherlock you suggested is a much better fit for what you do. Another good option might be a Rossignol One Magtech. I liked that board when I demoed it. Great edge hold. Decent all around board for intermediate. I ended up with a Never Summer SL. I doubt you can find it over there though and it's out of your price range.
Are you a comparable rider (All-mountain freerider sticking to groomed runs, trees, powder)? If so...why the SL as opposed to the Cobra or Heritage?
