I am currently a 9 handicap and in desperet need of new irons. I've hit the AP2s and the CBs and i can hit them both very well. But i was wondering how good do you actualy have to be to use the MBs. I know everyone says that you need to be very good but how good do you have to be. If any of you have the mb irons i would be interested to know what your handicap is? thanks
