I know where you got those specs, and that site normally has good info, but I don't think these are correct. Hogan always used a 37.75" 5 iron until they were purchased by Callaway. I was a full time club builder, fitter and club repair expert for many years in Fort Worth, TX, and there are a lot of Hogan clubs here, and I've worked on many of them. I don't remember ever seeing stock irons with those lengths.
Another way to check is to line your Mizuno irons up against a wall or counter and measure how much of a "step-down" there is between each club. It should be 1/2". If it's 1/4" on some and 3/4" on others, chances are the grips were not seated all the way.
This is a very interesting question, I hope after we answer it you will have some data or have a great answer for it. I would have to say the group where the pros hit the long ball and the 80's golfers hit the short balls would win.
I hope he gets the W, I enjoy watching him play. I also like the type of person he is. I hope he can get a few more W's.
I actually follow Fowler on snapchat he is always out doing something fun and having a good time. I feel he lives life to the fullest. I would love to be able to hangout with him off the course and drink beers.
I hope this makes sense. I would like to find a teacher who, first, really focuses on what the student is actually physically capable of doing, and, two, respects the physical changes and limitations of the old golfer.
Last year, at 70, and after two years of taking golf seriously, again, I knew that I had fallen into bad ways of doing things. I paid an instructor (he has all the credentials) $600 for two series of lessons over the summer. He helped me a lot, BUT we hit a wall. He insisted that the only way was to hit with big muscles, never with arms, and with substantial side bend, like a baseball swing. Plus his ability o communicate to me was limited. I am in fair shape for an old guy and was able to incorporate some of this, of course. However, I will be finding another person. -Marv
