Iron Golf Shafts – Matrix Program F15

The Matrix Program iron shaft has been with us for some time. The 2015 Matrix Program F15 is a subtle evolution of what has been a very successful shaft. Matrix, acting on club builder input, creating balance points in this version of the Program that will easily build into D2-D3 swing weights. The earlier Program shafts were white. If you had tested the Program and liked it, as many did, you lived with the white. The change to a neutral color, a shiny silver gray, removes an entry barrier for many.

The Matrix Program F15 is available in three weights, 80, 95 and 125 grams. As is typical with most shafts, weight and stiffness are interrelated. One thing you will notice when handling this shaft is the wall thickness. In carbon fiber tubes, wall thickness creates hoop stiffness and torsional rigidity. The Program F15 has both, the torque numbers are as low as it gets, and the hoop stiffness negates any possible ovalizing during the golf swing. That means the head is going to follow your hands. When you square off you hands the head is going to follow. The impact wave coming up the shaft is solid thud.
