It's true, you feel it in your arm more. That's part of what makes it more 'tactile'; the wood is closer to an extension of your hand and arm and is a more organic experience for that reason, and provides much better touch. Obviously, the more you play with it, the more you develop the muscles that are in accordance with the racquet you use. But it does put the focus of play on the mental more than the physical and is a neutralizer to athletes so that a librarian has a shot against them. I suspect that's what a lot of today's more 'athletic' core of players may object to about the use of wood, but all the more reason to make the switch. And while its harder on the arm, there would be MANY fewer player INJURIES that keep them out of tournament play for long stretches of time, which is bad for their game and bad for the sport, which needs the top-name players healthy to sell tickets. (The SPEED of play and POWER of the vibration to the body is what's causing so many injuries...wood's vibration against another wood is much less than against the speed/power coming at it from today's racquets!)
Also, the point that he's an older gentleman...this suggestion of the use of wood is to MAKE IT HARDER (not EASIER, as someone like him would naturally want, at his age) for PRO players. What a non-ranked professional can do with today's technology is great, because it makes BETTER play more feasible and comes quicker to players who would otherwise not be as good. But the pros are so good, that they almost need balancing in the other direction to keep the sport interesting. Call it a 'handicap' as in horse-racing, but it would make the sport more interesting and challenging...and that's better for the development of the players' game and more exciting for the fans.
It's a win-win situation, and is so obvious to me, I cant believe there is not greater support for this. Except that human nature does tend to go with "I'll do the easy thing rather than the one that takes work" almost everytime. We are lazy and want things handed to us.
if tennis is to remain a sport about refinement of the senses, wood's the direction. if its going to become about the domination of power, then today's technology has gotten us there. this is a CULTURAL issue that is true of this planet in general, it is not comfined to the tennis court. Wonderful if tennis would set some example about the proper management of power. But I dont think it will happen, in any case. It's certainly nice to talk about, being a dreamer.
