Can anyone provide me a timeline of the “formula” changes to these balls over the last 4 years? Seems like at one point their purposes flip flopped? Or so a Titleist rep told me once. I’ve got some 2021 ProV1’s that I played with last week. Was getting more distance with my irons than I did with 2023 ProV1x. Almost 10-15 yards on average. Trying to sort it all out.
