Yeah, the classes we've been taking are Argentine tango, and I'd really love to learn the difference between that and ballroom tango.

That said, I can't really imagine other ballroom being lead with the torso in the same way. Waltz is more of a whole-body lead, and swing (I know, not technically ballroom) the hold is so open that I don't think I could follow it that way. It's hard to explain with words; I don't quite have the right vocabulary....
