Z-Star is worked really well for me last year. No bad things to say about it. Played the regular and the divide last year and will this year again. If you are considering giving the divides a try do it! Personal preference of course but some may never play anything but a white ball and nothing you can say will change their mind. The alignment aide for putting is obvious but if you have any trouble at all tracking the ball it does help with those optics. I didn’t stay at a holiday inn express last night but my better half is an optometrist and approved that statement.
