I finally succumbed to common sense and opted for a shorter driver shaft. I went back to 42.5 inches (from 44.5) Loss of distance was negligible, but percentage of on center hits increased.
As I continue to plot my way through TGM I have noticed that I have started to hit my irons too low. I simply have more forward shaft lean at impact than before. I know that can be overdone, but I prefer to err on that side of things!
So I was thinking of weakening my irons to pre-a five iron is really a four iron days! Has anyone done this? Would love some feedback!
