I'm Back!Hi everyone- please excuse my absence... After not having flown a trip in over a week, my employers decided I needed to work, so I got sent to Columbus, OH... Just got back VERY late last night.
I have scanned through the responses posted during my absence, and have made a few notes that I wanted to respond to myself...
First of all, I have been in contact with Bonni, and her break was a clean, linear break, NOT A SPIRAL! She should be walking without crutches in less time than I was even allowed to begin putting weight on my leg.
Big E- The fractures occured before the fall, while still upright. But there was still quite a bit of torque existing, as the inside leg was twisted at almost a 90 degree angle toward the outside leg.
None of the respondents in the group reported any recollection of a "boot out".
All of the fractures were the inside leg, twisting toward the outside leg. (Big toe direction, but little toe side caught)
My 174cm skis were rated as a 12M ski, with a 64mm waist.
There has been a lot of talk about "drawing" the inside ski back. I think this is also a misunderstanding of how the body works, and the best position to be stacked in for power and balance.
Just like creating an artificial tip lead by pushing it forward, I believe that pulling it back unnaturally creates as many problems.
The tip lead should be relative to the position of the pelvis. When allowing the pelvis to be positioned in its strongest attitude, the tip lead should reflect that attitude. Drawing the inside ski back at this point can tend to overload it by virtue of the fact the leg and ankle can not bend freely in the boot to release the pressure from building in the forebody of the ski. It also promotes excessive closing of the pelvis, rsulting in the need to make an opening movement of the pelvis as you transition form one turn into the next. It can also lead to what I have referred to as a deflection.
The term "deflection" that I used in my initial comments may not be the best word to describe what I want it to. Please let me try to describe what I mean. Boy- I sure wish I could just draw a picture of it like John Madden!
Though the inside ski is edged very similarly to the ouside ski and pressured during a carved turn, it only bends similarly to, but less than, the outside ski. To make them bend the same would require absolutely equal weight and edge angle. But a 50/50 weight distribution is not physically feasible, as the inside leg will become significantly weaker by the position it will be placed in. So may we stipulate that the inside ski is not going to make the same arc, without some added guidance in the form of a steering movement?
That steering movement may take some force, given that the ski may be tipped at a fairly extreme angle. And with an aggressive angle, the ski cuts into the snow. While in that attitude, the ski is very resistant to getting turned inward, but could easily break loose and move outward.
Since the ski does not necessarily want to go along with the outside without some coercion, it naturally wants to travel a longer radius than the outside ski.
When the ski gets edged to that degree and pressured, what are the chances it will ever move more actively toward the center of the turn? More likely, it will straighten out, and move outwards. This is where the trouble starts....
If the pressure is more than necessary, and the ski does pull back, the leg stresses to control it. It can become unstable and begin to move erratically. Back to our earlier thought- if it's tendency is to move outwards, and we have just created an unstable ski, then the likely outcome is that the skis will cross. But as the inside ski is pressured, it will more likely cross UNDER the outside ski. Not OVER it! And the more edged the inside ski is, the more likely that will happen.
In every case I identified, the outside ski was on top of the inside ski. This is what accounted for the marks left on Noodler's ski, that he and I discussed. That the marks were exactly where I thought they would be confirmed that his inside ski had also gotten underneath his outside ski. At the beginning of our conversation, he was unsure which had gone where...
I hope this has clarified some of the points I attempted to make...
