I regret that I don't have much time here--my "trusty" computer is now undergoing major surgery at its IBM birthplace, after 1 1/2 weeks of attempts to fix it over the phone, and I'm on borrowed time.
But since I worked with Phil and Steve for nearly 15 years as a coach of the Mahre Training Center at Keystone, I will toss out a couple comments here. First, remember that the Mahres raced in '70's and '80's, and race techniques of the time relied heavily on steps and various 100% weight transfers at turn initiation. Stepping and lifting a ski are deeply ingrained in their muscle memory, and you can see it in this picture.
On the other hand, I remember maybe 12 years ago, during a MTC camp, when Phil INSISTED that he does not lift his inside ski! A few camp participants had observed the lift, and inquired as to its importance, and Phil denied even doing it. Then he skied a few turns to see, and sure enough, he noticed his ski coming off the snow. He was surprised!
That says a lot. "Lifting" the inside ski was not an intentional move, even then. Transferring the weight TO the new outside ski as he crossed over into the new turn was something he focused on, but lifting the inside ski "just happened."
Indeed, this whole incident arose when the Mahres were emphasizing that the body should flow DOWNHILL, crossing over into the new turn, while many of the camp participants were moving UPHILL in an effort to transfer weight. We had done a lot of exercises involving distinct weight transfers and steps to the new ski, and in this sense, those exercises backfired.
This is precisely the reason I am critical of emphasizing "lifting" the downhill ski to release and initiate a turn. Even in the Mahre Training Center, where Phil and Steve remain adamant about the importance of weight transfer in good skiing, we started to soften this focus, way back then, especially for intermediate and lower skiers. Where we had tried to get everyone to be able to balance exclusively on the outside ski from turn start to finish, we started to emphasize a 2-footed balance to start the turn, becoming fully committed to the outside ski only for the second half of the turn. The results were much better flow and turn linkage, and as speeds increased, the commitment to the outside ski naturally occurred earlier in the turn, as it should.
As I've often said, weight transfer is largely a RESULT of a turn, not a CAUSE. It results from the forces of gravity and centrifugal force that increasingly conspire to pull us to the outside as the turn progresses. More speed means more centrifugal force, so the pull to the outside happens earlier at higher speeds.
Finally, with all their emphasis on weight transfer, it is ironic--but instructive--that the turn the Mahres made famous--the "White Pass Turn," named after the family-owned ski area in Washington where they grew up--involves an initiation 100% balanced on the DOWNHILL (inside) ski, with the weight transfer delayed entirely until maybe half-way through the turn. Often the UPHILL (outside) ski would be lifted for the first half of the turn. This turn, too, was not something they "did" intentionally--they'll swear up and down to that! It is the result of world class athletes with incredibly trained skills showing the versatility and adaptability that is the hallmark of all great skiing! They claim to have laughed when all the up and coming racers of their day started PRACTICING White Pass Turs--which they had never practiced themselves--and applying it as the "right" way to ski--when it is still USUALLY the "wrong" way! It would be like the all of us trying to perfect the "Bode Miller hand motion" he demonstrates when he is teetering on the razor's edge of disaster!
PS--By-the-way, surprising as it may be, the Mahres are fraternal, not identical twins. They look nearly identical, but they aren't (sorry, Bob Peters!).
