Interesting lessons. As always.
First, smooth. I, and the teachers I have chosen, have always emphasized connection, technique, and the feel of the dance. Makes me feel great to dance with (according to my primary teacher who is not known for dishing out complements), but not always competitive. Thus, we are going back through everything adding in more styling. Without losing the other aspects. Both are needed, just that in my case we emphasized the one over the other more than he typically does. He didn't really have a choice: if I don't like how something feels to dance I get cranky. (Caveat is that sometimes something is a new feeling and I just need to get used to it.)
WCS. Working on it with Pro at the moment, will likely pick it up with New(er) Guy soon. WCS is the one dance where I have experience independent of Pro, though it is from many years ago. Pro's expectations and mine did not initially always mesh (bit of an understatement). It is astounding how difficult I became to lead because of how tense I got.

Four attempts later, we are to where I think he thought we would start. I don't necessarily love all of his choices, but I am at least following him better. For all I know, the choices he is making could be more in line with what I would experience in the WCS community at the moment. He has certainly danced it with "cross over" dancers, including professionals, who have more recent WCS community experience than I do. New(er) Guy saw some of what we were dancing and commented that he would have to learn it--I said not to worry, he didn't need to; we could dance the more basic material.
Rhythm. Team match approaching which is when I brush off my rhythm dancing. I know it would be good for my smooth for me to do more of it, but there's only so much time, $$s, and dancing I can do without injuring myself. I have offered to do my best to fill in slots for New(er) Guy. I dance with him a fair amount, and have competed with him, thus he was willing to treat me as one of his regular students. I have suggested, however, that he give the others first dibs and I'll take what he would otherwise have difficulty selling. There's nothing there that I wouldn't benefit from dancing, so why not? Turns out the "so why not" is because I have a brain like a sieve and truly don't remember learning some of this. Just as with the WCS, once I calm down and follow properly it all goes better, but oh my!
