I have this real bad habit of washing out the end of my turns. The only time I really avoid doing so with regularity is when I am going very fast, if I am going moderately fast it seems that my turns start out nice and clean but always end up with me kicking the tail out. I hate it!!!! It kills my times, slows me down when I am free skiing, and has gotten me in trouble when skiing choppy snow...that's why I usually just go full tilt thus avoiding the unpleasantry's of my deficiency.
BWPA saw it first hand when we skied together at Hunter, and I am sure so have others that I have skied with. I really don't have any good footage to illustrate what I am talking about, but maybe someone can discern errors that are causing this in this video of me at the start of a GS race. Thanks.
