I have the UST Mamiya Recoil ESX 460 F3 shafts, same as what I have in the JPX925HMP irons. I was fitted into the shaft, and would say my swing speed is slightly below average. The shafts feel great for my swing.
I'm now to the point where I don't hesitate to pull out the 19* or 22* club. I had my doubts at first since I was spraying the balls far left or right with no idea where it would end up. But the turning point came when I started swinging/looking at them as just another iron instead of the...
As painful as a kidney stone can be (I've had several), this is the one case I wish you had a stone instead. Stay strong and good luck, you can beat this!
If I had to pick one word to describe these irons it would be 'confidence'. I just love how they feel and perform. In fact, as soon as my hand grabs the head to pull the club out of the bag it just feels right. Confidence from the moment I hold the club.
I like the window seat, and enjoy watching the scenery pass by below. I try to pick out landmarks along the way (Half Dome in Yosemite for example). But if the flight is more than 2 or 3 hours I'll select the aisle....so my wife can poke me when she has to get up and use the restroom.
