Erik and Alan make good points. I also think it's worth the exercise to try to rank dances, and individual figures, by difficulty as a way of thinking about what makes a dance hard or easy.
For example: Which is easier to teach (or to learn): chain, hey, right & left through? That analysis is worthwhile, even if sorting your cards by such rankings is problematic. --Jerome Jerome Grisanti 660-528-0858 http://www.jeromegrisanti.com “Dance like no one is watching...
