I concur with all of them. This is my 3rd season and had 40 days last year. confidence on speed and definitely dynamic turns is the key. the DT controls your speed, and if possible look for an area where you can practice this. and if you feel you got it down on a semi-steep blue,go to a black run and do the same thing. It may be a bit frustrating at first but once you have dialed your turns on black it will come naturally on easier runs towards the lodge
. goodluck and have fun!
