I asked. In a busy competition like Blackpool 360 couples. 20 on the floor at a time . 12 needed from each heat. 1.1/2 minutes to decide.How do you do it in the Waltz for instance. Easy. I look for the correct rise and fall. If it is not there i look no further, that usually illuminates half the field. What if one couple are doing a group down the middle of the ballroom. You know , the usuall Fallaways and so on. For starters on a crowded floor it wouldn't be possible and shouldn't be tried. If it was tried it would not impress me. What about Professionals. We would expect them to be fairly proficient in what they do. Yes and have you watched a Foxtrot Final and seen how basic most of their groups are and again with the correct rise and fall.I think the 2006 final at Blackpool proves that. So, in the Waltz Commence to rise at the end of step one. Continue to rise on the next two steps and lower at the end of the third beat. And a straight knee at the extent of the stride. Then bend it as the weight arrives. All from the technique book and i will be looking for just that action, if it isn't there. Goodbye.
