From facing couples: Square Thru 2 to a wave; Cast 1/2; Centers Trade; Step and Fold.

Catch XY: From facing lines or 8 chain thru: Square Thru X (hands) to a wave; Cast off Y quarters; Centers Trade; Step and Fold.

Catch The Lock XY: From facing lines or 8 chain thru: Square Thru X (hands) to a wave; Cast Off Y quarters; each wave Lockit; Step and Fold.

From the comet formation (achieved from a column by all Circulate 1/2, then center 6 Circulate 1/2): Inside Interlocked Triangle Circulate (ignore the very outsides).

Flip The Comet: From a comet formation: Centers (in mini waves) do a Comet Circulate; close Point does a short Flip (in) while the far point (comet tail) does a long Flip (to the very center on the far side).

From various formations: Start as in Exchange the "Original formation" i.e. (Split) Circulate in the starting formation until passing the crossover point; as dancers cross over, they immediately start Circulating in the named Anything formation. For example -

Exchange To A Column - From parallel waves: All Split Circulate until each dancer in turn becomes a trailing center; trailing centers 1/2 Split Circulate, Hinge, and Extend (no hands) and continue to do Column Circulates until a total of four (Split) Circulates (including the center crossing action) have been done. When started from formations with very centers, those very centers lead off like an Exchange the Diamond, going around the other half of the formation. When the formation does not have very centers the call starts with a 1/2 Split Circulate (which gives very centers) and continues like Exchange the Diamond.

From any adjacent dancers: If your partner (side-on adjacent) is the opposite sex, face that person (Quarter In); if your partner is the same sex, Quarter Out, i.e. face out.

With Reverse Magnetism -- Reverse of above, i.e. If Partner is same sex, Face In; if partner is opposite sex, Face Out.
