UST Mamiya Recoil 440/450/460 ESX Graphite Iron Shafts

The UST Recoil graphite iron shafts really changed the performance of my older Mizuno JPX 850 irons. I had the older set of 850’s in storage, not using them anymore. I’m playing Mizuno 919 forged irons, great clubs. I installed the UST Recoil shafts in the 850’s just to try out and the 850’s are playing better than the forged 919 clubs! The Recoil shafts feel like they have more punch and distance with less effort.

Advantages: More distance with a good flight.

Disadvantages: A little less workability.
