Scott Brown with MMT graphite shafts in new Japanese company ‘Proto Concept’ irons

Last month, Rickie Fowler made the switch into Mitsubishi Chemical’s MMT shafts in his custom Cobra Rev33 irons, and Scott Brown is the latest to turn to the MMT graphite shafts at this week’s Waste Management Phoenix Open.
Our tour photographer Greg (AKA @pga43) snapped the photos of the new shafts this week, and along with the shafts our members were curious about Brown’s irons: Proto Concept, a new Japanese company with a website coming in March.
Here’s some photos of the shafts and irons from this week’s Waste Management Phoenix Open.
You can also take a look at some of Proto Concept’s woods, irons and hybrids in our forums here.
As for the MMT graphite shafts, per our photographer, “a number of other players may/will be putting these MMT iron shafts in play, including Scott Stallings.”
