Did you ever flo iron steel shafts. My modus 120 had a lot of oscillation in them when i did 1 of my irons. I have my driver pured right now have two hybrids that i am scared to do anything with because i hit them great 1 of my irons i have pured and i haven’t picked up yardage but can tell it loads different......switching out of the modus and going to a dynamic gold black gold frequency matched tour iron shaft and was thinking of either pureing or spine align at minimum
