Andre We use shafts made to our specs by Rapport ( much wider frequency range then standard). They are specified to be 3* or less torque and high flex point over the full frequency range. If you Fit the shaft properly, to be back to straight at impact, the high flex point gives the best performance and the launch angle built into the club head. If you use different shafts and build them to the same frequency for the player he will get the best performance from that shaft but it may not be as good as other shafts because the flex point is not as high.
