I played a round using both AVX and Tour Speed. For me, the Tour Speed held greens better. I've already decided on the X for 2021, but in a separate comparison of AVX to the 2019 V, I preferred the V to AVX around the greens as well. Your results may vary, but unless you are a low single digit handicap looking for the best spin, it would be worth trying each for a couple of rounds.

The Tour Speed wasn't so good for me to buy a second box of white balls. Yellow is much preferred for my vision.

Thanks Don O that's why I was asking because they have yellow now.
