Hi Dave, I bowl in Devon, so I'm quite far away from you, it was watching your video of the Oddyssey that helped me decide to give this ball a try along with all the good reports. What drill is on the ball you used cos you style is fairly close to mine from what you wrote.As I don't see a lot of really heavy oil I'm considering changing the surface to 2000 grit to make the ball a bit more versatile, what would your opinion be on this. Thanks for your help.
