Mizuno swing weights all over the place

Posted by terps2703


I ordered a set of JPX 900 hot metal irons with recoil shafts.  The swing weight of the 5 iron is D3.3.  The 6 through 8 ions are all between 2.4 and 2.7, the 9 iron is D3.3 and the PW is D4.7.  Is this normal??

How the heck are you measuring the swingweight that accurately?

I've only ever known them to be measured in full unit increments.

Only way I can think of is using the new up to-date Digital swingweight machine,

Mizuno catalogues only state when showing the specifications, swingweight varies from DO to D3, wedges have a slightly higher swingweight, can go up to D7,

Hi

I can't talk for Mizuno US, but our factory in Scotland is pretty thorough with checking through the assembly process.
