Along the same lines as "go where you're needed", I often tell dancers at some point during the evening, sometimes even at a "beginners' workshop", "If you don't know what you're doing and someone comes towards you and looks like they DO know what they're doing (pardon changing person with the pronouns),.. GO WITH THAT". It brings a smile and dancers seem to remember it. This, of course, is apropos when not specifically talking about end effects.

Hi Em,

Beneficial Tradition is great fun, but I'd suggest is best left for a crowd that has successfully dealt with end effects with minimal guidance. I'm not sure the end effects are, in any event, much more difficult than navigating the B2 crosses(?). That, to my mind, is a question of familiarity with unusual orientations, which comes from contra experience and/or an a priori natural spatial awareness and a firm sense of right and left!‹

ADPD, as I recall, is pretty easy and, as you say, needs the warning -- as with any multi-progression, or extra-minor set daliance, dance -- that you need to be aware at the ends and, at its simplest, go where you're needed! 

Often forgotten, as well, is to provide guidance to the non "out" dancers to self-recover when the "out" dancer is not there when/where needed!  :)

Bonne chance!
