I have a combo set of AP2 for my 4 and 5 irons , and then 6,7,8,9,PW are the 710 MBs. I have the Project X 6.5 shafts in them. My last set was the 690s 4,5,6 and the ZB 7,8,9,PW . I had the Original Project X shafts in them and loved the flight. The new irons shafts do not have the same flight and are not flighted. These shafts ballon, What should I do, maybe go to the 7.0 in the 4and 5? The 6 and 7 I dont mind as much cause I can controll them a bit more. Any answer would be great. My swing speed with 5 iron I think is what you test with or was it 6 , anyways it was 90, my driver is 112 to 116.

   Next thought I heard the original owner of Project x is the owner of KBS now and is making a stepless shaft very simlar to the first Project shaft. Would anybody be able to confrim this?  Titleist Tech Guys and Gals, PLEASE help im picking up strokes quickly.

Thank You, Dave
