The intent of Appendix II, 2b is for shafts to perform symmetrically with respect to bending and twisting properties, and the goal from a manufacturing standpoint should be to achieve this objective to the extent that it will make no difference how a particular shaft is oriented in a golf club.
However, due to manufacturing tolerances, it is not always possible to make symmetrical shafts. The best method to measure the symmetry of a shaft is to compare the CPM variation around the shaft's circumference. If the CPM variation is 3 cycles or less when measured in the six planes illustrated, then the shaft is considered symmetrical for playing purposes. If the CPM variation ranges from 5 to 20 cycles (which is possible), the desired CPM value should be positioned towards the target, or parallel to the face plane for consistent flex results within the set. This is the best way to neutralize non-symmetrical shafts according to the rules of golf.
Therefore, as long as you have not oriented a shaft in any of your clubs to produce a biased result, such as promoting a draw or slice, then you are playing with legal shafts.
