Hello Britt, I appreciate your previous response, just seeking some additional clarity. I had asked about current MPF 85 S iron shaft vs the Parallel tip MMT 90 S shaft, both of which are on the GolfWorks website to see how the profiles compare. Also was considering the Grafalloy ProLaunch Blue 82 gram S iron shaft as well, assuming that plays softer with higher launch than both the MMT 90 S and MPF 85 S or even the soon to be released MPF 78-ish gram stiff shafts?? I am seeking a mid-high launch graphite shaft that is more mid spin and will not balloon, yet will stand up to a quick aggressive tempo. Appreciate any additional insight. Thanks very much.
