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!
