You might make it to 70..if your lucky..
Back on topic...I plan on using a yeller ball when I start playing again, white is just to hard for my eyes to track, and yep I wear glasses.
That would be cool, only Srixon and Bridgestone have been making higher end optic balls so far that I have seen.
I was surprised when an older caddy at my club told me he hates when people use yellow balls. He says they are a bit easier to see in air but harder to find in grass and rough, especially in the fall.
As someone who generally plays yellow golf balls, I find this to be true.
But last weekend when I hit the wrong ball because someone marked theirs a little too close to how I mark mine, I remembered why I went yellow in the first place.
