True, true. I think of Patryk Ploszaj and Anna Kaczmarski, but can't think of any other couples. People like Andrej Skufca & Katarina and Marat Gimaev & Alina excel(led) in Latin and Ballroom respectively after being World Champions in 10-dance and then dropping one style. The desire to be the best in one style can lead you to drop the other(s). I dare someone to win both Latin and Ballroom at Worlds, or Blackpool, in the same year. Ha! Then they wouldn't even bother going to the 10-dance Worlds, for the fun of it. Teeheeheehee. FTR I don't think it's impossible.
