CJC you just post the same thing over and over gain man. Just put it in your sig that we should all use a SW of 320 or higher and be done with it. How many times do you need to post this?
also you are wrong about being tired by swinging light sticks as LeeD just illustrated. But I will take it further..the reason you are wrong is because you probably are not initializing your swing with your hip and core, when you do this, you get so much free power that if you are using a modern racquet that is lighter you can pound the ball with minimal effort.
Heavy sticks are nice for players that swing slower and don't use heavy spin. I use heavy spin, swing fast and use my body to hit the ball instead of muscling it around with my arm. It sounds like that is how you hit because that is what happens when you use a light stick and muscle the ball.
I hate how people make rules about a game like tennis. We all hit different and that is what makes the game so cool. Verdascos Sw was 315 on the pro tour.
THERE ARE NO RULES TO WHAT WORKS FOR YOU!!!
