All seem to be in line with the definition but never seem to get called. Probably Explode the Wave to a Wave is superfluous as it's simply a Lockit equivalent.
I use Snap the Lock to a Wave quite frequently but find it a bit disturbing that no-one else seems to be using it (as far as I'm aware).
Any thoughts?
Case 1 and 3 are probably not called because they're so quick, and it'd be hard to get the entire phrase out before the dancers finished the call then realized that you said "To A Wave".
Case 1: is usually just a Lockit or Cross Lockit, or better yet, an Explode And Step To A Wave (or Touch).
Case 2: I call "Snap The Lock, Centers To A Wave" all the time.
Case 3: I've heard callers say "Horseshoe Turn, Centers 1 & 1/2". I don't necessarily like this since my definition of Partner Tag is 1/4 In + Pass Thru, and 1 & 1/2 ends Facing, not in a Mini-Wave.
