I was intrigued by the Even Flow line I took a punt and got one for my M5 and have been very very happy with it. I love it so much I was happy to see it was an option in the Tour Edge hybrid I was chosen to test. It performed in the hybrid as well as it did in the driver, so much so, when I ordered my @GolfSub70 3 wood, I got it in that as well. So, you can see I'm a convert. But, I'd get fit rather than go out on a limb like I did.
Now to try my luck with the new Riptide.
