Max and I skied in Montana today with my brother and 3 of his children. My brother and his oldest son are what the skiing world would call intermediate skiers. They can ski pretty much all groomed terrain but the stem is ever present. Ideally we would have liked them to have moved quickly to the phantom move and to spend the day on lifting and tipping. Neither of them have had their alignment done by a trained PMTS alignment tech (or by anyone else) and neither of them has PMTS made footbeds. Without this alignment and footbed work neither had any real shot of balancing on one ski while lifting and tipping the other.
Can we give them some solid instruction and make sure that they progress over the next week? Absolutely, but what they will be able to do and how far they can progress will be very limited by the alignment issues (which gets corrected with first a proper footbed and then boot canting).
Both Max and I saw first hand today how step one for all skiers is footbeds and alignment work. From there you have a platform from which you can physically produce the proper movements. Without it, most have little shot. Harald has said over and over that roughly 90% of skiers need some form of alignment work. Max and I both know that we could not ski without our alignment work (which has been significant on our boots).
I know that I would trouble balancing on ski and lifting and tipping the other with my alignment left uncorrected. With it corrected it is easy (and I have spent countless hours practicing it).
From reading many posts this year there are a lot of aspiring PMTS skiers that want to progress and are even dedicating time to do drill work but that also have not gotten their alignment done. As the topic of the thread states, if you can only do 1 thing to help your skiing, get your alignment done!!
For someone that has not had alignment work, it may be very hard to understand the significance and how game changing it is for one's skiing. But any PMTS skier who has had the work done will tell you that it is a game changer.
Again if you can only do 1 thing over the next year to help your skiing, get your alignment done by a trained PMTS Tech.
