Marmot, I really respect your reaction to my first post. You have a good attitude, and that is the main thing. If you get some direction, I'm sure you will improve rapidly.
It is true that I was assuming other "stricter" breakdowns of the 1-10 scale. But, this one doesn't fit either. It doesn't only matter which runs you will ski or even attack (it is evident from the last 10 seconds of this clip that your spirit is good and you will drop into terrain that is above your level), it matters if you are skiing them or they are just rocking you. Style? If you are skiing effectively, this is the right style.
Again, I don't want to - and don't have time to - go into detail, but here are a few glaring issues:
You are just almost always way out of balance, usually making a linked series of recoveries - often not recovering. Balance is what skiing is all about.
Again, are you surviving the decsent, or are you riding a ski, flowing over the mountain?
No wonder your tag line is that you think the sign of real skiing is being exhausted. This couldn't be farther from the truth. Good skiing is about effective movements, which also happen to be the most efficient. Of course there is athletic output - increasing as the steepness of the terrain and speed of travel increases (and short radius turns obviously repeat the cycle more often) , increasing the effort needed to resist the external forces of gravity etc. And, the longer the day goes on - or the race course extends without a recovery break, the more total muscle weriness eventually sets in. But, the individual ski turn in microcosim when done right, is an efficient use of the kinetic chain conserving much energy. You are probably much more tired after much less time.
Now this brings up the point about fore/aft balance in particular. Because, just as I pointed out that your weight is way back when you are trying to ski powder (and that this puts a lot of unnecesary stress on the quads), you are actually always too far back.
Your poles (very important in this equation) are almost always way out (and up) to your sides, or even back behind you! You have to get them forward and down. Think of holding a serving tray.
Next, your arms are not only up and out to the sides, but they are flailing around. You have got to quiet your upper body. Release of one edge and transfer of balance to the other in efficient skiing is not accomplished by big exaggeratted up/un-weighting and then violent twisting (this is not necesary!), but a relaxing of the old stance leg, drawing of the center of mass downhill while rolling onto your new outside ski's inside edge, and then letting it - the stance leg ski's sidecut - do the turning. [Here is not the place to go into how best to accomplish this, but, for one way - my preferred way, check out the PMTS "Phantom Move", it is a foundation]. It is called the stance leg, not the pivoting or twisting leg. Ride the ski, don't swing them around. Or, ski the ski (on the snow), don't create a new sport of acrobatics with skis on - for this you don't need snow or a mountain. Stand in your living room, jump up, twist the skis and swing them around one side, land, then repeat to the other side. Much cheaper. [Even jump turns which are sometimes needed because of the steepness and extreme narrowness of certain terrain, achieves the release and transfer by the rebound of the energy generated by the gravity of the mountain and your previous turn against it, but all the while maintaining a downhill face and quiet upper body performing only counter
There are other important issues, but I have already gone on longer than intended. I highly recommend the videos/DVDs "Anyone Can Be An Expert Skier" 1 and 2. http://store.yahoo.com/snowshack/harb-ski-systems.html
To end off on a positive note, I noticed that your balance was better, although still lacking, at the 1:45 mark of the new clip, where you are skiing on very gentle terrain in shallow powder. Watch yourself there, it is closer to the way.
