I need to get on a launch monitor, I think I could benefit from a heavier shaft. When I go with a light shaft I feel like I got all of out synch.
Exactly what they did for me. You want to talk about whippy. I went with the heavier ones as well. I wasn't looking to gain SS, like so many are. I think if you have a faster transition at the top, like myself, the lighter shafts were impossible for me to hit without changing things up drastically. They aren't for everyone.
That's one of the beauties of the Miyazaki line...there IS a shaft for EVRYONE!
