Just my take yes 1 g can make 20 points kg-cm ^ 2. So for some it can make some difference for those that actually match heft. Most don't worry about it and go with what they play with unknowingly. Because my head hurts. 😝
Here's Justin Rose's build out sheet from a Spanish clubmaker I know when Rose played TMAG in 2013.. See the specs for a player that can tell the difference. (BTW....even myself as a hacker can tell the difference as I MoI match for heft. I watch the change in center impact as head weight, shaft weight etc etc changes. To me this is real club fitting. That's just me. Note the swing weight change and heft change. Just to show an example. Joe Hacker should be able to take advantage of said fitting factors as well as elite pros and it still shouldn't cost and arm and a leg. JMO.
