Edberg, as you say, had a beautifully smooth serve-volley game. Wonderful natural talent. However, I would say the best serve-volley performance I've ever seen was when McEnroe destroyed Connors at Wimbledon in the early eighties. He had earlier beaten Lendl in the semi-final fairly easily.
Poor Jimmy never had a chance and I was amazed when several months later he took McEnroe to five sets in the final of the US Open.
Oops, the Lendl semi-final was a year before, I think. He killed some New Zealand guy in the final that year.
