I went into my Grandaddy fitting wanting the Mavrik Pro irons after hearing about them at the presentation the night before. My fitter obliged me by trying the Mavrik irons then the Mavrik Pro's but quickly moved me into the 2019 Apex Pro's. I selfishly wanted the unreleased irons for the cool factor at first but those Apex Pro 19's were a perfect fit for me and I absolutely loved them and my game improved because of them. I would assume Callaway would want some or even most participants to be using the new gear but I can assure you that if the older stuff is a better fit then that is what you will get.I just don’t see how the next line of clubs that will be replacing the Mavrik’s will be able to compete with this years line up. When your are getting fit at the granddaddy is the new line the ones you are being fit with/into? I can see a lot of granddaddy participants wanting the something from the apex line or Epic line
