Have the Kk Shaft in my irons now, . Looking at the MMT , what might be the differences? Thinking of flight, feel and relative stiffness. I’ve read the MMT player a littler stiffer, if that’s the case would an MMT A shaft compare to the KK in reg?
The KK R flex and the MMT R flex are very similar in their profile. The MMT might play slightly firmer based on the deflection data, but not by much. The MMT actually has a little higher torque, so that could offset the firmer feeling. The MMT A flex is more flexible than the KK R flex. Both the MMT and the KK are considered mid trajectory shafts.
