cleochiro, I would print out the PDF’s that we come out with each year in our update and slip them into the back of the book. As soon as I finish the new fitting book, I am going to take all 800 or so MPF’s measured to date, combine them and redo them in individual PDF’s by each manufacturer. Then, every year I will simply update each companies master. Also, currently I have well over 100 additional #5 irons from the past thyat I have collected to add-in to each respective manufacturer, but I have not measured them yet. My eventual goal is to have all the irons from each manufacturer from 1950 or 1960 and on.
