First, the "Two Footed Release" may be well beyond your capabilities. In fact, it may hurt your skiing, if you don't have a weight transfer, and balancing ability, book 1, or tipping ability, book 1 and 2. Many people think I just write these books to make money and that most of it is fluff, well I have news for you, every page in my books holds information you need to know, if you want to teach yourself to ski. I have never written a page to fill space.
You might think you have done a TFR, but it may well include an extension or a push to a-wedge and a full upper body rotation. You have to perfect the TFR, with PMTS movements not your old movements you learned from Trad. teaching, and don't just think you have already mastered a TFR. The TFR is a test of all the right PMTS Essentials, I'm amazed people think they have mastered it so easily and quickly, without even having a qualified professional PMTS instructor to validate this. Without a reasonably good TFR you will never progress to the BPST. We spend many hours in our camps teaching the elements of a good TFR and many don't get it the first camp they attend.
I'm sorry I make it look so easy in my videos, but I have skied for 61 years and trained for skiing my whole life, I already developed PMTS movements years ago, yet the TFR is still challenging, especially done slowly. The biggest difference between the TFR and a BPST, once you have the basics perfected, is more tipping and higher angled tipping earlier.
