O3Speedport from Prince is one of those tennis racquet technologies out there that really seems to hook people in. With larger O Ports than their first line of O3s, these Prince tennis racquets are said to be more aerodynamic and have an even faster swing speed. This Prince O3 Speedport Red, in particular, is a very fun tennis racquet to hit with. The Speedport Red has a 105 square inch head and open 16x19 string pattern that are very accomodating to all parts of your game. If you like to stick back to the baseline, youll find yourself hitting a heavy ball with plenty of spin. More of a serve and volley game? Big serves make it easy to come to the net and get a put-away.
