"Do WCS dancers do shines?" I had been dancing country western (including WCS) for maybe six years before I even heard this term used at one of the few Lindy Hop lessons I went to. I'd say, no, West Coast Swing people don't do shines. Especially at CW places. We have line dances for that sort of thing, I'd argue. On the other hand, when you watch West Coast Swing "peformances", the partners will separate and do things by themselves. I guess you could call that "shining". When I dance WCS, I am looking for the partnership. Dancing apart doesn't make much sense in that context. Same thing for Argentine Tango, where you never dance apart. Maybe the hard core Westies, or the competition people will tell you something different. My peception of salsa is that it is a lot more "look at me" based than West Coast. That is, geared towards the external, rather than internal. (That is a generalization, and there are many exceptions, as with any generalization.) The term "Shine" is related to the concept of "it's your moment to shine", isn't it? It's kind of like the term "hijack", I think, which you don't hear used very often, or at all, with some dances. This term seems to be used primarily by salsa and Lindy dancers, and I think it reflects the character of these dancers.
