Just curious what most pros racquets feel like. I know that the model in the store is no where close to the one the pros are using on TV. I have heard some use lead some just have the manufacturer beef it up internally so you can't tell from the outside. Just wondering if they have them set for low power on average. I did swing a teaching pros stick and it was super heavy and had more power than I expected. At what point did the amateur decide to add so much weight that the racquet was over 13 oz? It seems that most pros have a super heavy stick. Is that the progression? Do young 5.0 players that have the talent eventually figure out to add a ton of weight? Or do some of the touring pros play with 10 oz sticks? Just curious.
