Having at least understood the excessive swing weight issue, looked at the lengths of my new clubs. The new G30 4 iron looks and feels scary long (in addition to heavy). Compared them to my Eye-2s and they aren't even close. So I made some measurements and plotted out the length of each iron (on the vertical axis) versus the loft angle of each club. Did it for both the old Eye-2s and the newly fitted G30s. It looks like this:
The first shocker is that my new 4 iron is almost like a Ping Eye2 2 iron! Even I know long irons are hard to hit. My newly fitted 4 iron is just a 2.5 iron (and a heavier one at that) in disguise. No wonder you can put a G30 4 iron onto a mechanical golf swing robot and it flies farther (for the marketing folks sake). Except the machine is infinitely strong, which is the flaw in that.
So pondered this for a bit. Why need longer irons in the first place (forget for a moment the Doc said so)? If you think about it, for the people, shaft length only matters for the shorter irons so a tall person doesn't have to scrunch down so much. That's about it.
At the Doc, the G30 7 iron flew 15 yards further than my old 7 iron because it was, in fact, like my old 6 iron. It makes sense now.
Getting closer, but problem still not solved.
