I was fitted with 716 CB irons with 1/2" short in length but standard lie. After playing for almost 2 months, I felt it's light for me compared to my others iron set so I got them measured and surprised that the swing weight of PW is D0 and others are C9.
Could this be the problem by the manufacturing site when they shorten the iron but not adjusting the swing weight back to original specification as D2?
