Night Glow balls are worth the money!
I played for the first time with these balls and was pleasantly surprised. The ball glowed solidly for 4 and a half hours. I never lost one and we played in complete darkness (on a course I know well of course). Ball flew around 70-80% of a conventional ball. Used a GPS course map on my palm pilot and it was great! Add 2 clubs for distance and have a blast!
