Used MG C4 Golf Balls
MG has reformulated the core to produce a much higher velocity than ever before. The urethane cover of the 3-piece Tour C4 is very thin, with an extra-large core making your drives go extra long. The aerodynamic 332-dimple design of the MG C4 golf ball helps deliver those extra long drives. This ball flies straight and high, and lands hot making your drives go longer.
The ultra-soft urethane cover, with improved durability, gives you the high spin you need with your irons and wedges to stop the ball on the green— with great accuracy. Off a wedge, the MG Tour C4 spin rate is in line with the Pro V1 (within 250 RPM). On fast greens you can back the ball up 15 feet or more with either ball. And around the greens, the soft feel of the Tour C4 makes it easier to control and chip the ball closer to the pin for more one-putts.
