Interesting.. you know nothing about Amer. style and yet, you have critiqued it !!..
What you witnessed, was the Comp style, NOT the " Social " style ( which was my reference and point ) and that was my comparison.
The Silver/Gold levels, were designed to be different from Intern. style, ya know, it's called CHOICE..
Both chain schools do teach Intern style and, both have turned out world class dancers ( one, 3rd at Blackpool ) the other, 8th in the world in Latin .
In case you do not know, the variety in the " Smooth and Rhythm" (as they are called ), give more types of dance as choices, thereby giving appeal to a wider audience, and after all, is that not what "dance " is all about? .
Just for your info, I am a dual Fellow in 2 English Soc.in Ballroom and latin( English trained ) and same, in the American style , and a former Examiner .
I do respect your opinion, but I think you need to research the other style before you come to a full conclusion ( there are ex. on this site in the vid section ).
By the way, I do hope you realise that EVERY dance we teach in the Intern. style , was NOT originated in the UK, and "we " subsequently changed them, some for the better and otherwise, some may say not !!
