Hi Nolo. Messing with our hands and arms are we? Me too. We place so much focus on lower body discipline, and refining our lower body movements to the Nth degree, that we tend to ignore what movements are happening in our upper body, in particularly our arms and hands.
What I've been focusing on, (when I have the time for myself), is adjusting my arm height to better reflect my whole body posture, along with maintaining arm width that better reflects the role my arms have to play in my skiing.
Some other thoughts,,,,if our arms are too wide and high, tension in the shoulders and upper back will develope. This pulls the shoulders back, just like dropping our hand and arm down by our hips does. This also distracts from the softness and functional movement needed in our upper body and spine and interrupts the integration between these parts of the body with the nessasary movements happening elsewhere. Neither of these two upper body postures serve our skiing in any positive way IMHO. Both I know very well.
Taking a page from tai chi chaun, sink the shoulders and hollow the chest (gently rounded shoulders). What I also like to bring from tai chi chaun, is the idea that if there needs to be arm movement to swing the pole, I try to keep the elbow following the hand. This brings positive direction to the arm movement that should coordinate well with the intended direction. Otherwise I try to swing the pole with my wrist.
For myself, if I have to make any big movement with my arm to swing my pole then I haven't been accurate and disciplined enough. The old hands up in my forward vision is timeless.
So my only advice my friend, would to keep your hands much more forward, and adjust the height to the dynamics of the turn. This should help solidify your center and drive your balance even more down to your root. Though you are already a very rooted skier IMO.
We should get out and ski this week if you are in town. Also,Tai chi classes start up this Thursday evening at 7:00 if you two are still interested.
