Regarding the Coaster Step in WCS: It is OUT not because of it being difficult and the Anchor is easier to learn. It is OUT because the Lady on count six is stepping fwd and leading herself down the slot, thereby not allowing the Man to lead her on count one. Only some ballroom studios teach this incorrect method and once it is in Muscle Memory it is Difficult to quit. Leaders complain whenever they end up with a Lady that leads herself (doing the coaster step at the end) and does not allow him to lead her. The Anchor step is like a period at the end of a sentence. It is at the end of the figure. It is a STOP- STAY RIGHT THERE. The Anchor allows the couple to use leverage and have a stronger connection. The Lady (or man) may choice to do a syncopation (break ending) something fancy, a Lean or Lunge and the Leverage in the Anchor is necessary to allow this. Your teacher is lacking in WCS education. The KING of SWING Buddy Schwimmer teaches the Anchor step. His son Benji recently won “So you think you can dance” The coast step is used in the whip at counts 3&4 and the Locked whip. However it should NEVER be at the end of a pattern(figure). Find a new teacher, if yours is unwilling to change this MAJOR issue in WCS. Bet she is with AM. When someone is going to learn WCS the most important thing that I tell them is if you get an instructor that has you Coaster on the End of the pattern Run. WCS has many styles Swing, Pop, Funk, Western. But the Coaster on the end is a big NO NO.
