Well Mizuno can adjust a few degrees on the irons, but i didn't want to mess with that. So I am just going to adjust to the new irons over time. I am sure I will miss club for a few weeks. My Taylormades are crazy strong. My 5 iron is my new 4 iron, so its one club difference.
What I did was, basically created a spreadsheet with my current golf clubs (lofts and lengths), and distances. Then matched them up with what I have now. Golf clubs are going to have typical gaps. Usually a bit closer gaps near the lower lofted irons, maybe 9-10 yards between the 3 and 4 iron, and 11-12 yards between higher lofted irons. Just how the irons tend to play.
The mizuno 4 iron matches up spec for spec with the Taylormade 5 iron. So I know that club will go with in 1 yard of that. So i can gap it pretty close. When i went out last night, I was pretty close. I had to think, Ok my Taylormade was a 7 here, So i probably want a 6 iron. If I am off, I'll adjust.
I'm thinking of creating a small cheat sheet to carry around for a while. But my guesses were pretty on last night. Most of the irons are 1 number designation less, 7 iron for taylormade is 6 iron for mizuno, but add a few yards. So its like one number less plus 3 yards.
what I need to get now is some new wedges. I got a 6 loft gap between my PW and my 52 degree. I'm thinking of going with Edel wedges ;), though I might buy a mizuno 50 degree as a gap wedge, then get two Edel wedges for around the green.
