I started back playing about 9 months ago after a 4 year break from golf due to back surgery, " disk replacement". In 2005, I had purchased a new set of Callaway Fusion irons and was fit at my local golf shop. My specs for my Fusions were .25" longer and up 2deg lie. Well,... I have been working with a PGA pro instructor weekly for the past several weeks and I practice appx 3 hours daily,... tryin to build a muscle memory of the swing changes that my instructor is trying to instill in me. When I started back, I didnt just want a band-aid type of approach,.... so he had me start from the basics of grip, posture, stance, and then concentrate on ball contact on short shots and then slowly work from there upwards. I recently wanted to purchase me a set of irons with more feel than the titanium face Fusions provided, but would still be forgiving. I went to a local demo days and tried many different brands and models of irons and finally decided on the Mizuno JPX-800 pro irons. I was fitted by their rep and he said my specs were standard length and -3 deg lie down. Two different brand reps also fit me very closely to what the Mizuno fitting specs were. I then went to my local golf shop and had them re-fit me since I thought my specs were way off from what that golf shop fit me for 4 years earlier. They did and also came up with very similar specs to the Mizuno and other companies.
My question is this: From a technical standpoint,..... Is it common for a persons club fitting over a few years to change that much? Was just curious as to what aspect affected the change the most,... my back surgery or the lessons? By the way,... I'm 6-02, 230lbs 40 years old and my driver swing speed is 106 - 110mph. And a little info on my swing is I used to hit a fade and sometimes a slice and now I have a consistant draw or straight ball flight or when I get too handsy I can get a hook. I'm just a kinda technical person and was curious, because I am striking the ball much better with the new irons.
