So if you add weight evenly, the increase in static weight doesn't significantly increase power? And if you add weight to the head, you can get more topspin?
It's just that in my experience, adding lead makes a racquet easier to use.
Not exactly. What I'm saying is that with a racquet that is less powerful to begin with, adding weight to the head adds some of that crushing power. Adding it any other places decreases how much it changes.
What I was trying to say about topspin was that with that extra power needed top be controlled, and by a strange coincidence, higher swingweight (which is what adding weight closer to the head increases by a greater margin than other places) means that the racquet also has greater inertia through the swing; you just have to start it swinging, and as long as you don't make any signifigant changes in energy (such as stopping the stroke) then it almost
wants to swing through the ball. So it adds more power, and makes a circular stroke path (such as the windshield wiper) take more energy to start and stop, but less energy to maintain.
I oversimplified it earlier, I think, because you were right in the things I said, but I know they're not 100% right..
Regarding the commentary on even distribution-- It does add power, but not in the same way. Swingweight and static weight both effect power, but swingweight does it differently. Think about it this way-- if two sumo wrestlers ran into each other, then it'd be like the sprite commercial. Now imagine that one of those sumo wrestlers were to, instead of running, slide into the other who was running, then all the force of the slider would be in the space of the runner's legs: a greater pressure would be applied (same weight, smaller space). Now imagine that a sumo wrestler and Lleyton Hewitt ran into each other: Lleyton would go flying because the sumo wrestler would have such a difference in weight. That's what happens with the ball and the racquet. The racquet weights upwards of 200g, and the ball weighs 56.7. The ball goes flying. But if the sumo were to get even bigger, then lleyton would go flying further, ne? But even still, it wouldn't be as far as he would if the sumo wrestler were to tuck his shoulder in and focus all his weight around Lleyton's chest.
The added weight will increase power, but not quite so much, just like the bigger sumo threw Hewitt further, but not like he'd concentrated the weight.
