Checkout the racquet swingweight customisation tools at the following link. RacquetTech.
“Swingweight is the most important parameter to customize because it has the most influence on how the racquet feels and plays most of the time — i.e., when you are swinging and hitting the ball. But good players want all their racquets to feel the same at all times — holding it still vertically, holding it still horizontally, swinging in a straight line, or swinging it in a circle about some axis. Holding the racquet by the handle with the head pointing to the ground, all you feel is the weight. If you hold the racquet horizontal to the ground, you feel the “pickup weight,” which is defined as the weight times the balance point. If you swing in a short straight line as in a punch volley, you are primarily pushing a weight, not rotating it around in a swing, so you feel its weight and balance. When you swing in a full stroke, you are rotating the racquet around an axis (at your wrist, elbow, or shoulder) and what you feel is swingweight.
Using this calculator, you can determine where and how much weight to add in order to match two or more racquets in weight, balance, and swingweight. This is the ultimate equipment service that a coach or racquet technician can provide for a player.”
Tennis Gear offer a service that measures swingweight and allows players to customise their racquet weight.
