hmm.Just to cast another penny in the pond ...
I have no training and am lousey at descriptions of movements on skis, but I do take my K2 710 Comps out every season to reinforce my appreciation for new equipment. ( Justification to purchase yet another pair of skis ;-))
There are few differences in the method of turning, but there is a big difference in the intensity (Hasn't that already been stated here.)
Bend a straight ski, and it arcs, bend a shaped ski, it arcs as well. Bend for bend, it's a wash, but it takes little effort to bend a ski with a good amount of sidecut. (power steering). The old ski lets me down at high angles (boot out) I feel really stupid as I pick myself up off my butt. Then a smile creeps in 'cause I know I was doing the same thing, just different intesity or amplitude.
Somethings that bugs me are the one footed, two footed and the balanced VS forward pressure. I like to ski crud, so perhaps my style is more like controlled bouncing, but two feet are always envolved, old or new. On the subject of two footed weighting, The idea is that a single edge fully loaded will grip better into firm conditions than twice the edge length (two skis) and half as much pressure. I don't have a problem there. I'll put as much into the light foot as is consistant with snow conditions and steering requirements. (steering/ directing/ coaxing with the inside foot). I do know that if I fully commit to one ski, and that one edge lets go and starts to slide, well, I just slide with it. If the weight is split, and one leg goes, I get jostled around in a way I don't like.
Two footed skiing is soft snow skiing, so that's how I like to practice. It's all a matter of degree.
On the fore and aft concepts, Both the new skis, and the old ones, ski better with pressure on the shins of my boots. Better might read "more responsive" I just can't seem to get around that. When I hear someone state that the new skis are static in their arc size, I wonder if a bit of forward pressure might brighten up the day. (tighten up on that drum!)
Let it be added that committment to the fall line is a useful technique no matter what the tool. If I bring the uphill hand out and down the fall line at the start of any turn, Any ski seems to do the right thing under foot.
That "technique" really works on steeps and crud and in the trees.
Boy it's raging a blizzard outside my office window!
No breaking news, just fuel for the fire.
