Would be a fun watch. Some of the tennis would be bad (for pro standards), and it would be funny to watch Rafa serve and volley. Fed, Llodra, Stepanek and a few others would do reasonably well. They could bring back Pistol Pete, Rafter, Johnny Mac, and Edberg for good measure. Racket sponsors wouldn't care, as long as they used that particular company's old wooden racket, and it had a their logo on the strings. All the major companies had woodies.
