"No Foot Rise will enable the couple to stay in the same position that they start in. If this is not done correctly they will lose there centre and spend the rest of the turn trying to get back to where they should be. Is it possible to dance without NFR. Yes, but it will never be clean and tidy"
On the contrary, it works just fine with NFR, as I mentioned the open reverse turn with the lady on the inside is always danced with NFR on that step. And there is no losing of the centers as a result!
What does happen however, is that the man-woman dominance dynamic will change. There is no problem with this if we simply consider the position of two androgynous human bodies with relation to each other - the problem comes in only if we wish to preserve gender roles in the character of movement. By using THT instead of NFR on the inside of the feather finish, the man achieves the character of dominance in the subsequent outside partner action which is considered desirable in the male dancer.
When the lady does the same action, she uses NFR, and achieves the character of swinging up to her partner rather than being dominant over him.
