I had one before I got my Odyssey No.7. It worked wonders for me in 2006 but at the start of last season I couldn't get the swing tempo right so had to get shot. AG gave me Â£45 against my Od. The thing I like most was the alignment aid. I put a line on my ball anyway and this made lining putts up even easier. If you are not aiming straight, it is so obvious.
