Has what improved my dancing?
If the question was the classic english hold - parallel thumbs, to oustide of base of hand, man's hand inside elbow, lady's elbow bet, then the answer is that that, and the intent behind it, has been little short of revolutionary to my dancing.
But I didn't learn it from a message board. I learned it from directly experiencing that hold with world champion dancers in a series of lessons over a number of years. You can feel the dancing in that hold, even before there has been a single centimetre of joint movement.
