I am in the process of purchasing a new set of irons and have cut my options down to the TaylorMade RBZ and CB irons. I am a 15 handicap and want to know if I should go with RBZ considering it is a game improvement club or the forged CB. I am worried the if I purchase the RBZ in a year or two I will need to purchase a forged club due to the fact that I outgrew the game improvement RBZ. I guess what I am asking is should I go with the CB, and force myself the play good golf with them or go with the RBZ and play good golf now and purchase forged clubs later. Any help is greatly appreciated, please give your honest opinion. Please correct me if I am wrong about any of the above irons. Overall, I just want to improve and have fun with the game.
