From twin diamonds: Points facing in walk straight ahead to footprints of point facing out across the set, points facing out Flip the Diamond, ends of the center wave do a Diamond Circulate taking the adjacent center of the wave with them (Ah So type action). End in parallel waves.
From diamonds: Designated point (e.g. in-facing point for In Roll to a Wave) Circulates as other point does a Turn, Step, Turn toward the designated point (i.e. both points move as in In/Out Roll Circulate); center dancer who is facing the designated dancer (the circulator) will step ahead taking the other center along, and then they Hinge in the spot vacated by the circulator. (Note: Centers facing designated point always do what is effectively a Diamond Circulate.)
From one quarter tag formation: All Scoot Back then those facing out Trail Off, walk ahead and Slide Thru with the person they meet from the other side. Those in the wave do an all four Crossfold and then Slide Thru. Finishes in various formations depending on the arrangement of sexes for the Slide Thru.
From a one quarter tag formation: Those in the center wave step forward and Scoot Back with the outside two (the outsides now face out and the centers return to re-form the center wave). Those facing out Peel Off then walk forward and Slide Thru with a dancer from the other side. Those in the wave do an all four Fold and then Slide Thru. Finishes in various formations depending upon the arrangement of sexes at the start.
Usually as a call added on to another preceding call which finishes with dancers in a formation which has identifiable centers and ends. Centers Partner or Single Hinge as the ends Backtrack (U-turn back by turning inward). Finishes in various formation, usually related to the diamond formation.
