I don't like this one.
The caller would want the facing dancers (Side boy and side girl) to start the Dixie Grand. However, the definition says "Those who can Right Pull By". In this setup, with the boys having a Right handed miniwave, all the boys can start as well.
If this is going to work without errors, you need to add something to make the boys release their hands, such as "Slide Thru, Pass Thru (Boys only), Dixie Grand" or Slide Thru, Heads Roll (!), Dixie grand".
The way to call this type of Dixie Grand is Those facing start
Dixie Grand (that eliminates any possibility of the Boys
starting it). TC
