I have been very curious about some of the major differences between the new Pro V 1x and Pro V1 and the old versions of them. With the prices of both of them being quite high. I was wondering if it is worth it to spend the extra few dollars on the new ones or go a little cheaper and stick with the older ones. I have hit both, and they both feel incredible at short and long game, it's just if I looked at track man and saw the numbers, would it be worth it? I absolutely love both of them. They are simply the best golf balls in golf.
