Hi Bob,

Thanks for the question. This is a question that we still hear from time-to-time and the quick answer is no, you do not need a specific swing speed to play the Pro V1 or Pro V1x. It is important to note that the Pro V1 and Pro V1x golf balls are designed for all swing speed players. 

Check out this blog post where we caught up with the golf ball R&D team to delve deeper into this topic. There is some more more great detail that will help provide additional insight. Thanks again!

I thought the video did a nice job of pointing out golf ball fitting begins withscoring clubs THEN looks at the driver performance...sonmany times it seems this process focuses first on the driver...thanks for the great video, I learned something new!
