abcdefg. Its good that you drew attention to the Three Step. As we all know the crazy books have us starting the Three step as man on the RF. and finishing RF foreward which then becomes the first of a Natural movement. Unless of course it has been changed. If it has not it should have been.Anyway as we come out of a Reverse into the Three Step we have two heel leads, on each of those heel leads we need to flex our knees as we will on the end of the following TH. which is a basic concept. Not to be done with straight legs. Do you agree
