[quote=mattennis;7229948]I have put the links several times in the past.
Thank you for the informative post. I had a look at the archives, searching for the links, but there's far too much there (over 200 pages) to make it worth the time. If you know of a link that provides results of tests done on ball-speed-after-the-bounce on various courts, I would be grateful. Player testimonies, though interesting, still don't provide the degree to which things may have changed. What may seem a radical change to one player may not seem so big to another, perhaps more talented, player. I would like to see numbers and facts.
