Full Set of 5 shafts for your 6-PW. AMT Black is the middle weight option in the AMT range and delivers a mid-high trajectory and spin. Featuring Ascending Mass Technology, AMT Black gets progressively heavier as golfers move from their long irons to short irons. This allows for increased speed and launch from the lightweight long irons and superior control and precision from the midweight scoring clubs. AMT Black ascends in 3-gram increments throughout the set from 4-iron through wedge and is perfect for the player that loves the idea of AMT and wants something in between the superlight AMT Red and tour-weighted AMT Tour White.
