As I said earlier, these drawings are a bit simplistic since I did not show any movement in the ankle, knee, or spine and the pelvis complex is illustrated by a single pivot, let's assume these joints would be contributing too.
#1 shows a straight run in a gliding wedge with equal edge angles, weight distribution, and steering angle. With everything being equal and symmetrical the skier remains traveling straight down the fall line.
#2 This over simplified drawing is intended to demonstrate an offensive/positive movement scenario where there is no movement away from the intended direction of travel. By simply reducing the deflection from the right ski via reducing the edge angle beginning with tipping the foot toward the little toe and causing the knee and pelvis to be pulled toward the right, the skier maintains the head mass in the same position. As soon as, immediately upon, the reduction in deflection from the right ski occurs a turn is initiated and results in a weight shift. We can argue the chicken and the egg affects here if we like as to whether the weight shift causes the turn or the turn causes the weight shift but this is not the point. My point is the weight shift occurs without an active effort to move any part of the body over the left ski to cause the weight shift. If you can visualize yourself simply rolling your right foot to reduce the edge angle of the right ski, or do it on your living room floor, you will see that movement alone, with forward momentum would allow the left ski to become dominant in it's deflection shifting the weight passively. Now the skier must simply balance against the left ski with slight counter balancing if you will, and the inside ski , provided it is allowed to move forward slightly as it wants to, will continue to flatten. In addition to this the turning forces and slope angle change will further facilitate the inside ski tendency to skid into a christie.
#3 Here in contrast to #2 the skier actively makes the first move to shift weight to the left ski which in turn causes more deflection from the left ski than right and a turn occurs. While the skier is balanced as well as #2, this method tends to cause the inside ski to hang up on the inside edge impeding it's matching. It also tends to cause a lateral push (brush?) that further increases the inside edge angle resulting in the dreaded edge lock wedge where the skier travels straight down the fall line even though all their weight is on the left ski, the edge locked right ski's deflection over powers the left ski.
NOTE: Comparing and contrasting these two techniques will reveal #2 skier, rather than increasing deflection on one ski to over power the other (antagonistic) the skier decreases the resistance from the right ski permitting the left ski to dominate. This is a notable difference! One is antagonistic the other is cooperative and requires less energy and effort. This is the beginning of creating the GO intent, which does not entail runaway speed down the fall line as some here have suggested, but makes turning easier with less need for higher edge angles to overcome the inside ski edge. So instead of ADDING more weight, edge angle, or steering angle to the left ski, the skier simply reduces the edge angle on the right ski to allow the turn to begin. Once it begins the weight is where it needs to be and the small amount of counter balancing needed is enlisted.
#4 is a trick question, don't do that.
#5 puts the weight solidly over the inside ski with the outside ski becoming an outrigger, don't do that.
#6 puts you on your butt. don't do that.
Let the haters hate.....;)
