Ski instructors have dismally low success rates with getting students to a higher level. Why? Because they teach an adaptive lesson and use adaptive outcomes that are at a low skiing standard and level. When I watch our ski groups skiing at camps it is obvious they ski better than most ski instructors. So why bother wasting time and money taking a lesson from PSIA when you ski better than the instructor they give you? Even if you get an instructor who is a reasonable skier, doesn't mean he knows how to teach you movements that will advance your ability.
I've been teaching recreational skiers for 25 years, since my racer coaching days. I know what it takes to change movements and what obstacles skiers go through to learn. I know what challenges skiers face. First of all, you have to realize, a skier can't change a movement pattern that has been adapted to for a poor boot set up, until the boot set up is corrected. That skier will make the same mistake over and over no matter who coaches them. But this is the standard at the US Ski Team as it is in PSIA.
In a PSIA lesson you will not get this changed. PSIA knows zero about boot fitting, alignment and boot set ups.
So no matter how good the "CARV" system gets, it's still a compromise until you have dealt with your boot set up properly and accurately.
An example, 3 out of 4 skiers that come to our shop need to have an "extended range", "T-Nut" installed into their cuff adjustment feature to achieve the correct position on their leg. We invented this "T-Nut application, and we have the hardware made to fit and modify most boot cuff adjustors. The boots that come with adjustments on the cuff do not address the range needed for proper positioning of the boot cuff to the lower leg.
Over 70% of skiers don't have their cuffs correctly positioned, this also goes for the world cup racer. Harb Ski Systems are the only ones in the ski industry that do this and know what it does for the skier. We know and have developed this system by hands on changes and evaluations. We also watch, analyze and coach PMTS movements with success to skiers who were not able to achieve them before the boot corrections were made.
o At our ski camps our coaches and technicians work together to determine the alignment that will work best and we modify it based on the turns a skier makes.
We have a long list of top skiers we have changed for the better since they have make the correct adjustments. For example: Reilly Mcglashan, Tom Gellie, Erik Schlopy, Sarah Schlepper, Resi Stiegler, to name just a few, and many others who are already highly accomplished but were not able to maximize their abilities. Even Mikaela Shiffrin benefited from our alignment analysis from my phone call over the ocean. Many accomplished skiers reach a dead end in their skiing and don't know where to turn. I've coached and met only two skiers (they were World Cup winners) in my career who didn't need alignment, so that leaves lots of skiers who can use help.
So regardless of your attempts at quick fixes, Carv systems or Camps by ex-ski stars, you are spinning your wheels until your address the mechanical limitations in your equipment first. The movements you receive, learn and instruction that gives you the correct movements, are just as important and are integral to the alignment. You won't achieve successful until you learn the same movements used by the really high end outstanding skiers and they all use PMTS.
