Neither shaft fit this player exceptionally well. This player's average swing speed should generate an ideal tee shot of about 245 yards. This player hit this particular soft regular shaft quite poorly. His launch angle was too high and the ball spin rate was excessive. His launch specs with the X stiff shaft were better. Both launch angle and spin rate were acceptable, so between the two shafts, the stiffer option is the better choice. The player's swing path, draw bias and angle of attack were consistent.
A better course of action is to seek out a stiff or regular plus flex shaft, something with tip section stiff enough to keep this player's launch down and with enough torque to help keep his tee shots just left of center but not with too much total spin.
