Been playing a cally Mavrick driver for the past few years. It was always good but I started to have issues with my drive in general for most of the summer. The driver also developed a funny sound.
Turns out it was cracked.
I did a fitting and was fit into a TSR3 but not wanting to spend the money right now I picked up a near new TSI3 head and had my old shaft installed.
So far I'm very happy, Driving the ball well. Need to experiment with all the settings.
Id say it was a good upgrade
