Peter. You will use more steps that are linear if possible in the Waltz. The Waltz being the killer dance for the tall with shorter partner.In the Quickstep the body contact is higher. It doesn't mater if you are a short or a taller couple. Don't let anyone tell you that the contact has to be down in the hips for the swing dances.. I was told years ago that if I need a role model pick somebody who is about the same stature as myself. I will never do a Fallaway like a very tall thin guy. Obvously there might be a wider body here to get around. I would never do a Fallaway down the LOD instead of diagnal to the centre. I had one ridiculace teacher who insisted that my first step had to be down the LOD. I said I have a tape of Michael Barr, and I can assure you he takes his Fallaway diagnal to the centre. That didn't go down to well.
Just for the record . What is the angle of the ladies right arm in your opinion in those shots of Warren Boyce 's partner Kristi. There are plenty to choose from. Best of luck.
