I am fairly new here, and this may have been previously discussed, but I was wandering if the pros (or top juniors) change their grips and swings and such depending on what court they play on. For instance, does Venus Williams use a more eastern forehand grip at Wimbledon than she would at Roland Garros? And, just wandering, what grip does Venus use (in general)? I know its a lot of questions, but I'm just curious. Thanks in advance.
