I've skied with Harald Harb (two full days) and one of his top coaches (Rich Messer, two full days) at one of his All Mountain clinics. I feel I have some knowledge of what he's offering. Has anyone else skied with Harald or one of his coaches?...or taken one of his books and given the routine an open, honest trial? I'll freely admit...I like Harald. I found him to be open, honest, friendly, and just a nice fellow.
It isn't pure marketing. During each of the four days, I skied better than I ever skied before. I'm 59, no jock and never have been, don't ski as well as I'd like to, and love skiing. The simple techniques taught in PMTS work. Period.
The techniques of PMTS have been vetted by a biomechanist, Dr. Robert Hintermeister. The instructional aspects have been vetted by an educator, Dr. Kim Peterson. Single mindedness?...maybe, because it works. It ain't religion...it's fun.
Ski race technique is rarely, if ever, taught to recreational skiers. Maybe it should be, and maybe that is what HH is doing. I don't know enough to comment. HH does have a race background...Canadian National Team member, pro racing, and coaching.
I know no one in PSIA hierarchy. I see PSIA instructors teaching movements suitable to pencil skis and rear entry boots to everyone. I see PSIA instructors teaching movements that must be unlearned for the student to advance. I see PSIA instructors teaching movements that many of them don't use themselves when they free ski. PMTS does none of this...it teaches movements that can be built upon.
PMTS only uses one-footed sking as a learning movement. It is not an advanced movement. It doesn't have to be unlearned like a wedge turn has to be unlearned. Harald himself leaves two carve tracks when he skis. HH's #2 video even demonstrates turning with weight only on the inside ski outside edge as one tool to have in the kit for times when that's where your balance happens to be.
PMTS promotes vertical separation of the skis to allow for angulation, but not horizontal separation. This is not having both skis locked together. It means that the feet as far apart horizontally skiing as they would be walking or biking. Horizontal separation of the feet when skiing causes the center of mass (CM) to be between the feet or above the inside foot preventing angulation for the most edge angle. It also puts more weight on the inside foot and reduces the weighting of the outside foot which reduces the potential curvature of the outside ski to limit turning tightness.
There is no rotary force initiated in PMTS. When the inside foot is tipped with the arch upward, there is rotation in the femur. That is a result, not an intended move. The skis are not twisted to turn on the snow. This is not "counter." There are two counters. Counter weighting and counter facing are different. The hips must be dropped to the inside of the turn to counter weight the centrifugal force of the turn. The upper body needs to counter face into the turn to properly position the body and the feet. I'm not explaining this well. Look at this: http://www.web.pdx.edu/~petersj/Skills/Videos/ULBC.wmv
Harald was a member of the PSIA demo team. He says didn't like what he saw, and quit. Regarding edge to edge, when does that happen? HH's technique for advanced skiing wants the skis to change to the new edge before the fall line is reached. That means that for a momentary time the skis are on their downhill edge, the hips are downhill from the body, and the body is facing uphill. This is just momentary until the skis cross the fall line already on the new inside edges. This might have been racing technique for many years, and is in HH's 1998 instructor's manual, but hasn't been taught widely to recreational skiers.
Ron LeMaster is a superb ski race photographer. He hasn't coached WC skiers. Listen to Harb and view LeMaster.
I'm not a trained PMTS instructor. I've been to a camp, skied with Harald, and liked what I did. Anything I wrote above is just my understanding and subject to correction. Ask your questions in a non-confrontational manner at http://www.realskiers.com/pmtsforum/viewforum.php?f=1
and you'll get a non-confrontational answer. You'll learn much more about PMTS from http://www.web.pdx.edu/~petersj/Skills/Lessons.htm
than I can tell you.
Anyway, it PMTS works for me. I now ski better than ever. We had a full-cert PSIA instructor as one of the students at the camp, and he told me that the PMTS coaches help him improve his skiing, and the PSIA examiners he's friends with and skis with don't. Those are his words...I didn't investigate for myself.
