You may need to switch to the optic yellow AVX if/when it's available everywhere.

Barry is right, AVX is the closet you'll get to a yellow ProV. I did see them last week in NH at my local pro shop, a dozen yellow AVX balls for sale. No I didn't buy it. The ProV1 is my ball and always will be, no need to change...

Anyways, I'm gonna guess the AVX are finally being released around the country now.

If you search on "yellow pro", there are a multitude of threads making this request. I'll limit my list of possibilities to - when the pros ask for it, it will happen. The other OEMs that offer a premium urethane ball in amber barely have a handful across all of the men's tours. As a course marshal at senior tour events, I don't know that I've seen 4 players out of 84. I will definitely be hopeful that the AVX will be my salvation for my eyesight issues. Please, no need for others to respond - Titleist has heard the request enough times.
