Ok so I got my 718 AP2's last fall, Vokey wedges, 910 driver Hybrid Titleist bag etc. I bought a dozen Prov1x, then won a dozen Prov1's which is now my ball and I am very happy about that. But I noticed recently that my local retailer is advertising the Prov1 at the new price and it says 2018 Prov1, and while the box is a bit different, when I open the package I cant tell the difference. Can someone kindly explain to me the difference between 2016,2017,2018? And how to tell the differences as well by looking at the ball? I want 2 things from this. The ability to get the best ball, and not be charged for a current model only to be sold a 2-year-old model. Thank you in advance.
