Actually, you know what I see in this series of pictures? l
Weight nearly 100% on the outside ski. Actually lifting of the inside ski. Lower legs creating an A-frame. Skis diverging parallel with an exaggerated step into the new turn. There is a very short, I guess you would call it a semi "carve", for lack of a better term.
Really, this was good, aggressive race technique in 1985 or so, when people used 210 GS skis. Can it be improved on with more modern technique and equipment? Of course. Quite a bit. The skiing can be much more efficient and because of better ski technology he could actually truly carve if he wanted to learn.
Is he interested? Of course not.
You know what you need to do HS? Find someone that used to ski all the time, but hasn't been out at all for the last 25 years. Take him skiing and say "what do you think?" He'd be like, "you rip dude!"
Realize, it also works pretty good when freeskiing 22m, 28m, 30m, and 35m radius sidecut fat skis......not going to work on a 15m carver.
Oh, and I can and do carve very cleanly when I feel like it....but I'm not trying to here....I'm going for high load carves with a locked body position, not focused on clean carves.
