Hi everyone! I need new irons. I’m currently using Mizuno MP18 irons and they are too hard to hit with me being around a 25 handicap. I’m interested in game improvement irons but don’t want to break the bank on brand new irons. I am also 6’3” with a 36” wrist to ground measurement so i don’t know if i should get them 1/2” longer or not. My swing speed is consistently around 76-78 so i also don’t know if i should buy regular flex or stiff flex and hope i grow into them. Any input would be greatly appreciated!
