I recently saw someone dancing their standard/smooth dances with the leader's hand palm-out on the lady's left side (as in back of hand on her shoulder blade), as opposed to the usual palm-in we're all used to. I was told this is the "latest thing". Curious, I tried it and I can see where this would help the leader keep the right arm in the proper position and not "droop" as is common among those new to dancing standard/smooth, but I see no other benefit than that. Is this the "newest greatest" thing, or just a practice hold as I assume it is? Has anyone else seen this?
