This is why I would like to see a return to perhaps a "reference" tennis racket made of one material, a standardized-size head, and standardized material for the string. That way, everyone has to play with the same racket type, and it will force players to stop emphasizing the power game so much and emphasize more the strategy-based game.
That's a bit too restrictive. What they could do is to decide on a maximum racket head size and then reduce that size slowly, with a few sq cm per year, until you reach the head size that was common during the late 80s. I think that was a period when there was a pretty good balance between the base-line players an serve-and-volley players. Of course it depends a lot on the ball weight as well.
LOL What an absurd claim. Oh, by the way, Bill Tilden was clocked (using film analysis) at hitting serve at 163 with your vaunted wooden racquets. Search: Bill Tilden fastest Serve
