Got a nerd question when company’s talk about where the sweetspot is located ,,on what groove on the front face is the sweetspot? And if the mass on the back of the club is above or below that sweetspot does that mean high or lower mpf?
All irons/clubs are different. No single spot. On irons, our goal is to have the cg at the center or slightly toe side of center and a slow as possible for the type of design we are doing. Generally if you have a mass higher in the back, it drives the cg up, which is a negative with regards to the MPF. Rearward cg as far back as you can get it translates into stability and higher MPF, generally, but it shouldn’t be higher.
If you have Ralph’s book(s) on the MPF and Playability, all the detail is there. Great information and explanation for nerds like us.
