The guys checked it out last night.
Off the tee, hitting with the same clubs, no spin, dinging... the ball with the more dots go further.
Approach shots are just about impossible to test like this, unless you have the the 2 balls sitting besides each other, so they really couldn't tell because of different distances.
I'll keep and eye open, I know I've ended up sitting on top of another ball once or twice, so if it happens again... I will check it out.
I'm just trying to think out the approach shots... I think that it will be hard to tell if more dots make a difference, because you are going by the yardage to pin and calculating from those figures, but I suppose.... if your using a house ball, that will drop sooner than a nike would... hence the extra dots. Then the dots for spin will come into the equation.
