The iM10 family of shafts are the first Project X shafts to feature Hexcel’s® incredibly unique iM10 carbon fiber, a very high modulus (stiff) and very high strength carbon fiber allowing for new possibilities in golf shaft design. Because of this, iM10 shafts offer unmatched stability in both a playable mid launch/spin design and a counterbalanced low launch/spin tour design—providing a variety of options to best suit your game.
Tempo is not how fast you swing it, it is how you swing it fast. Tempo will affect how you load and unload the shaft and is a big factor in which shaft will best suit you. A player with a quicker backswing and more aggressive transition will have a faster tempo, while a player with a slower backswing and smoother transition will have a more deliberate tempo.
Trajectory:
Trajectory is the flight of the ball and the peak height that the ball reaches. A player who struggles with getting the ball in the air should look towards a higher trajectory shaft, while a player who struggles hitting the ball too high should look for a lower trajectory shaft.
Spin:
Spin is the amount of backspin that the ball has. The designs of certain golf shafts can promote more or less spin so keep this in mind when looking for a shaft to maximize your game.
