Just ordered the MB Irons with Nippon pro Modus 3 Tour 120 stiff flex.
This is the best shaft I have ever used.I first tryed it in the new Miura Irons and Honma use it also.The 714 MB match these clubs.The only thing is missing is the I Omic grips.
Hope this helps,everbody should try this shaft.FANTASTIC
Cheers
Robert
