Hey C, Ha! I feel the same way.....stuck at Expert Beginner level!
I'd echo others here.........your looking good enjoying the ride but your not (committing to the turns to) Drive the turn. To me commit means getting more aggressive....more complete C turns and less edge of trail S turns.
Your letting the board take you down the hill. I personally want to Drive the board down the hill, by completing all turns and finishing each turn up hill while setting up my next turn while finishing the last turn.....not letting the trail width dictate when to change direction.
I'd like to know what board, width, scr, etc and bindings, boots your on........
