Mixed Iron Set Loft Gap Question

[Adam O]

So I will be ordering a new set of irons. I plan to mix Mizuno MP-20 HMB 3-4 irons with Mizuno Mp-20 MB 5-PW irons. That will leave me with a loft gap of 6 degrees between the 4 iron (22 degrees) and 5 iron (27 degrees).

 

What is the best way to close this gap? Should I bend the 4 iron down to 23 degrees or bend the 5 iron up to 26 degrees? I know that bending clubs changes lofts as well, so I will need to consider that also.

Hi, I would look for 4deg. between irons. This will usually give you a 10yd difference between clubs.

My choice would be to bring the 5 iron down to 26deg. and check all the other irons, 6-PW for the same consistency.

Of course if your clubs are dialed in for a distance you know and like, then making a 1 degree change to the 5 iron only shouldn't make a huge difference.

I think it depends on how far you hit your 4 and 5 iron. It’s as simple as that. Other than that Stay out of the shit, call the zoo.

Good choice for set break. Mizuno recommends blending sets between 4i and 5i.

As for what to do with loft gap,

Here are your lofts for the MB20s:

HMB  Iron  MB

19*     3i     21*
22*     4i     24*
25*     5i     27*
           6i    30*
           7i    34*
------------------

You would need to test out the set at the mix point to tell for sure. 

First you need to test out the MB 5, 6, and 7i yardages to find out MB internal gaps. If the MB 5i is a bit hotter than other faces, it could overcome the 3-degree loft gap 5i-6i and not be a yardage issue.

But, if the 5i-6i distance gap is less than 6i-7i, you might bend the MB 5i to 26*.

Otherwise, you might bend the HBM 4i to 23*.

The two HMB irons, being hollow-headed, might be a little hotter overall than the base MBs.

Again, test out the irons for yardage gaps. Don't bend unless there is a consistent gap.
