I've heard that the back-pass was being replaced, and little-em taught a potential replacement a few weeks back. How does this one go?
Personally I liked the back-pass as a beginners' move because it's a really simple one and easy to lead with the newest beginner, although it's not the most exciting move for intermediates.
The proposed replacement I saw relied on the leader stopping the follower from walking round, and also having weight on the correct feet in order to step from side to side. I found this hard to lead with people who hadn't seen the move before (maybe it's just me though
).
