I agree that I think the WDSF may be going a little over the top. Perhaps a passing fad or maybe the young people are just a bit too enthusiastic.
Passing fad? Its been developing over the years to the point it is now de-rigour. IMO the WDSF, however democratic its organization (which I am not convinced about) is destroying standard ballroom dance. [I can't say for latin.] I don't like to watch it anymore, no insistence on grace or expression - just who can do more contortions while moving at lightning speed.
it reminds me of ice skating - the WDC is the free program and the WDSF the compulsory figures.
