I love it!!!!
I stuck the X flex in a GBB II pro series 9.5 degree. I had never used an X-flex before, but all the figures added up. I was right to trust my instinct. This thing is a rocket.
I hadn't even tried the shaft when I put it in. All the details added up for me and I took a chance with it. I do need a bit more loft on the driver, but the spin rates were absolutely perfect when I hit a few on the launch monitor.

I am looking to buy a new driver with a bit more loft so that I get a bit more of an arcing flight rather than the fairly flat ball flight that I have just now, but want to keep the same shaft. Just need to find someone to do the work for me.

I now want to find a similar shaft for my 3 wood. I have currently got an NV in it, but don't really like it. Any suggestions would be great.

Get the Assassin for your driver now. It is the best thing you can do.
