Phil. Do you mean a Tele Spin. If this is it it is not difficult if you can remember that the lady steps on one (Waltz Time ) the man doesn't. he follows on two. The lady with her feet together on the toes does have a changing of the feet. I do this one from a Wrong Foot Lunge with the above technique.. It's a nice move. Richard Gleave says that it was more likely to have been an accident in the beginning, when somebody overturned the Telemark and suddenly found they had a new step.
