The Pro Kennex Kinetic 5G Classic is the same model as the original 5G with the same specifications. Excellent control and maneuverability with good power. Definitely a "players" racquet. The ProKennex Kinetic 7G Classic plays solidly and nearly vibration free. The Kinetic System is especially effective at eliminating the kind of vibration that can contribute to muscle and joint aggravation. The 7G has smooth handling middleweights with surprising power and good control. The 7g uses its greater Kinetic mass and extra length to boost power versus the less-powerful Kinetic 5G. Racquets include Synthetic Gut Stringing FREE!
