So, you're saying that most people who aren't pros don't use the windshield wiper stroke correctly? No offense, but that sounds a bit condescending. It seems like some people, especially traditionalists, are super critical of this particular stroke. Like if you don't do it exactly one way then it's totally wrong. I've seen quite a bit of variation on this stroke that seems to work well for different people. Hell, even Fed's forehand is pretty unique. He uses a strong eastern grip with elements of a traditional and windshield wiper stroke all in one. And no I'm not comparing myself or anybody else to Federer, but I'm just saying there's more than one way to look at things.
I don't think you quite understand.
What separates the pros between me and you is that they are playing at a level where the ball is jumping at them with 2k+ rpms and about 60-100 mph. Plus, these balls are placed on the dime. They have no choice but to use the windshield wiper.
Plus, a professional tennis player uses the wind shield wiper effectively and has had years of training in drilling that shot and has the strength to be able to generate his own pace from that shot. Most amateur tennis players simply do not have the strength to be able to generate a huge shot off the windshield wiper motion.
Most people don't realize all of this, and tend to try and copy the professional players. The problem they run into is that they lack the solid and basic fundamentals, so when they run into someone who has those solid and basic fundamentals who also has elements of the professional game, they get blown away.
To be quite honest with you, male professional tennis is a totally different type of game. It is not the same game that me and you play. This is why Lee's suggestion is not a bad one at all. Heck, most women on the WTA don't use a windshield wiper motion, and they could crush most of us without losing a game. I'm not saying it is impossible to generate pace with the windshield wiper motion, but it is much more difficult then hitting a with a flat finish.
