I think this is really cool, I wish a range around where I lived had something like that. I am not sure how much more I am willing to pay to use it though. Most of the ranges I have been to. Its not flat and there is not accurate distance markers. Its hard for me to tell where my ball lands sometimes and hard to get a good distance so this would be a good tool for those kind of ranges.
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.
