Swivels and/or cross-over swivels are done with a double open hold. There should be strong pressure between leader and follower. From my classes, I learned that the leader needs to planted into the floor in order to make swivels work. I find that if the leader moves his arms, it throws me off balance. I see it done both ways. Follows, which do you prefer? Or it doesn't matter? If the leader moves along with you, how do you keep your balance?
