It will be interesting to see if you still see white better than yellow in the sky ten years from now. For me, it is not even close or I would choose a white ball. They are easier to see on the ground.I'm still not convinced of this argument, at least through my eyes.
I've used plenty of different colors, and nothing is as easy for me to pick up in the sky and on the ground as white is.
The materials being what they are aside, I think it's a visually leap that would take a lot of convincing for a lot of pros who have looked at white their whole lives.
....and as I sit here, I am wondering if I see yellow and think range balls
