I see that the MPF ratings on shafts indicate whether a shaft is slice(S), none(M), or hook(H) corrected. I assume the (N) is a shaft with a low torque rating. In the correction factors (H) and (S) the higher torque enables more tip twist but how is the torque influenced in a specific direction, CC or CCW?
M or not correction for a hook or slice is a shaft in the mid torque range. S for correcting a slice is a higher torque rated shaft and H for correcting a hook is for a lower torque shaft. The Rules of Golf state a shaft has to play the same no matter how it is oriented. A torque rating on a shaft has to be basically the same in both directions to be conforming to the rules.
