I'm developing into a huge Shelley mark too. But just to pick some guys not mentioned so far:
Nigel McGuiness: His chainwrestling and counters are just amazing. Shame about his voice, but hey.
Xavier: I've gone from pretty much hating X to really enjoying his matches. I've seen a lot of innovative work from him lately.
Roderick Strong: Love the backbreakers, the energy, just a really, er, strong
worker.
