There have been a lot of advancements in shaft materials over the past few years. The increase in denser pre-preg materials is certainly not new. That being said, the new HexTow high modulus (stiff) material in the iM10 shafts offers a unique blend of stiffness for stability and strength with more feel. This allows the Project X shaft designers the ability to build stronger shafts at lighter weights without losing distance or accuracy along the way. There are two distinct models available:
Mid (Mid Launch/Mid Spin)
Available in 50 gr (5.0, 5.5, 6.0), 60 gr (5.0, 5.5, 6.0, 6.5) and 70 gr (5.5, 6.0, 6.5). Project X shaft designations are roughly Regular R(5.0), Strong Regular R+(5.5), Stiff S(6.0), Strong Stiff S+(6.5) and TX X(7.0).
In our testing the 50 gr is a true Mid Launch, while the 60 and 70 gram are more Low-Mid launch. The mid section of the shaft is very stable so you will not feel a lot of “kick” or release at impact. This is also NOT a counterbalanced shaft so swing weights will be standard at standard length.
Low (Low Launch/Low Spin)
Available in 60 gr (5.5, 6.0, 6.5 TX) and 70 gr (6.0, 6.5 and TX).
In our testing, both the 60 and 70 gr shafts are Low launch and Low spin. The shafts are slightly counterbalanced which will reduce swing weight 1-3 swing weight points versus a non-counterbalanced shaft like the Mid described above. Like the Mid, the Low has a firmer mid section, but lower torque for better stability and feel at impact for stronger players.
