Agree with your analysis, to a point. There's also extension happening in many of the turns, which usually leads to stance ski BTE pushing and stemming. It's one reason why PSIA/CSIA methods, which teach extension as a necessary "skill", never lead to world class skiing. The visual key is the knee of the new stance leg. If that leg straightens at all during transition, you're extending. If you extend by even 1mm, you'll undo a proper PMTS transition.
That "floating" feeling during transition is cool!, isn't it? However, do NOT rely on or practice that feeling - or any feeling. Rely on making the prescribed movements correctly, as verified by video or trained eyes.
As to what to work on next, I'd suggest Super Phantoms. I'd wager you can't do them reliably now. Mastering them will cure extension, stemming and wedge entries. That said, I defer to PMTS experts and echo previous posters who advised you to :
- slow down;
- master ALL the exercises in the books, in order, beginning with ACBAES1, page 1; and
- slow down some more.
You will only become a PMTS skier by mastering the drills at the slow speeds HH demonstrates in his videos. It sounds like drudgery but it's not. I've never had a more fun or productive ski week than when I watched my partner's PMTS instructors at the recent Green/Blue camp and echoed the drills that give me trouble, always at the slow speeds they were using. After hours of that each morning, an hour of free skiing demonstrated real improvements by leaps and bounds.
Skiing/riding fast is fun, but it doesn't teach you new movements - at least not good ones. HH at 65yo could woop your a$$ (or mine) on any race course or mogul run and leave you (me) feeling mighty embarassed. But he didn't get that good by skiing fast. He got that good by sking slow while practicing effective movements.
