As a caller it is my belief that the man has the responsibility of ensuring that his partner is safe during the dance. I believe that hand to hand with elbow clasps gives him much greater control as he 'Birls' with his lady, giving her a greater sense of security and faith in her partner aand in so doing, lessening the chances of her falling and hurting herself. Particularly important with novice dancers. As we all know it's too easy to get carried away in Strip the Willow.
