Backwards pivot slips can be snuck up on by doing falling leafs….
FYI, to pass on similar ‘sneak-up’ advice from an instructor in a past lesson at the onset of introducing a backwards pivot or spin. He said,
If you can do a spin on the flats, you can do a backward pivot on the hill. You start on the easiest terrain and work up to increasingly steeper terrain.
LF mentioned a couple of ways to ‘sneak into’ this move, from falling leaf. A spin is another way to sneak into it, because it seems that the edge change sequence for a successful backward pivot is much the same, if not identical, as that for a 360* spin, or for that matter, a 180* spin. The trick is to not catch the downhill edge which will cause an AOT transition. [[footnote 1]] To that end, avoid practicing on very, very flat slopes. A steep green or easy blue will help avoid the edge catching because the pitch keeps the downhill edges further off the snow. Once you are comfortable making 360’s, forward and backward, across the greens or easy blues, you will have enough confidence to spin backward on the much steeper terrain shown in the RM video. And you do not need twin tips to do it.
[[footnote 1]] An AOT transition is a remarkably inefficient transition described in the recent thread called Transitions: An (im) Balancing Act, illustrated in post #129 and formally defined in # 138.
