These Taylormade RocketBallz RBZ Irons were very easy to hit, have a large sweet spot and are very forgiving. The two-piece metalwood-inspired construction in these irons create a low center of gravity and a high coefficient of restitution (C.O.R.) I am a 15 handicapper and have been shooting my best rounds ever with the Titleist 712 MB Irons on sale. These are very smooth, solid irons. I've just bought the Ping G20 Irons on sale and they deliver much better distance than my previous Irons. I got a net 68 playing off 14.
