My swing speed with the 7 iron is around 84-86. I have CFS regular flex shaft in my I-20's and only hit my 7 iron 150-160 yards. I feel I can step it up on the speed if needed. I consciously slow it down for a smoother swing. I am seeing guys on here hitting 8 irons 170 -180 yards. Is this normal? My question is what is your swing speed, shaft flex, and yardage with the 7 iron? Please be honest because I am contemplating changing my shafts to a stiff flex, if needed and start cranking them out, if I can, IF my average yardage is not average.
