Leaders also monitor their connection skill, as well as question themselves on things such as, was the lead clear enough, did I goof up her axis, is my floorcraft good enough, etc. IMO, both the leader and the follower are dependent on each other.
I fully agree with you about the similarities in these two roles; anyhow that is the goal. Today my partners and my own experience is enough to maitain a quite balanced abrazo. But I still remember how hard it was during the first follower years and I can hear that it is still so for the new followers. These matters should be addressed in the follower training.
(There was a leader, who was easygoing, experienced dancer with one or two tricks. He talked through the songs and he always made me feel ok. So after a few terribly tandas I asked for a tanda with him and after that I was a normal me again! I called him for my Tango Doctor )
