Some people like to study stage tango movements because if they can't get people to pay attention to their low key, boring social dancing, they can kick it up a notch by flinging their partner into outer space (and other people)!
Does anybody really want to study how to dance well on a crowded dance floor anymore? Where the best dancers can express the music with the simplest movements while they are shoulder to shoulder with the couples around them?
Maestros Blas Catrenau and Myriam Pincen dancing on a VERY crowded dance floor. Perfection!
I don't know about others, but I think this is the highest form of Tango expression. I leave ambitions about winning championships and showing off for other people!
