Which Professional Association has a Spin Turn in its syllabus that isn't a Natural Spin Turn, Polished?
A NST would always be demonstrated from step 1, and would include pointing the toe of RF back after step 6, having shown the lowering of LF e/o 6.
The demonstration would also show the heel of the LF being released as the RF step 5 is taken HT (just like any other forward walk), and the demonstration would show rising e/o 5, and NOT rising from "there" (4) onto step 5 (ie rising e/o 4, up on 5).
Down on 5. Rise e/o 5. No Hover.
