So, I started thinking about this again once the thread was pumped up again this year. I was playing with my fore-aft balance some this year and was finding a slight heel weighting at the turn finish would really put some power into the tails, but that I was having problems getting diagonally across the skis to get into the next turn.
So I started working with the poles allot more. I found that the reach for the next plant seemed to help me move diagonally across onto the new edges, and defiantly added some rhythm that was lacking before.
That reach of the pole plant causes movement of the Latissimus Dorsi muscle. It gives you the opportunity to gain leverage and balance, assisting in an early edge/pressure of the ski in the top of the new turn. Keep your elbows in and your hands in front.
