The KE4 MAX iron and the Rapport shaft are both new in 2022, and do work well together based on our testing. We developed the Rapport shaft with VA Composites and it is extremely stable and provides a great feel. VA Composites produces some of the best high end product on the market and we wanted to tap into that experience, and use our experience, to produce a high performance shaft that didn’t cost an arm and leg. We are happy with the results. I have no problem recommending the Rapport iron shaft in any of our models, if the fit is right for the player.
I think the combination of the MAX iron and the Rapport iron shaft would appeal to anyone wanting an Ultra Game Improvement Iron and would benefit from a lightweight graphite shaft that is stable and provides great feel, along with the other benefits graphite composite shafts offer in general, like better vibration dampening.
