Mach Line shafts are hand made by NGS Japan. The 5 series is for the average golfer looking for a high quality shaft to improve their game. Lightweight at between 52 and 59g to improve swing speed with various kickpoints depending on the golfer's swing, the 5 series comes in 3 models, all available in regular, stiff/regular and stiff flex.
The 5040 is the all around model of the 3, designed with a low to mid kickpoint and balanced stiffness across the tip, center and butt of the shaft.
The 5250 has the stiffest profile of the 3, made for those with quicker tempos wanting a mid-high kickpoint, eliminating the left side.
The 5350 has the softest tip of the three, coupled with a stiffer butt for feel, low kick and high launch piercing ball flight.
