We compared the lofts of three #7 irons launched in 2020 from separate brands targeting the same level golfer. We found significant differences in loft strength.
This begs the question; does the number on an iron’s sole have any purpose other than enabling you to organize your set? We’d answer with an emphatic “no”. That’s why we keep telling you to get fitted.
Although this seems bizarre, club manufacturers have very good reasons related to CoG placement and clubhead material for setting unique lofts on their irons. But for you to take full advantage of those innovative designs, a fitting is essential.
