A couple weeks ago I received a sleeve of the 2019 ProV1x prototypes in the mail, and just this last weekend had the chance to play a couple rounds with them. The first thing I noticed and was pleased with was that after 2 full rounds with the same ball, there wasn't significant wear and tear on the cover. Comparing to a 2018 ball, the covers felt exactly the same in my hand, but the 2019 ball seemed to be more durable. The ball offered the same expected performance around the green and with approach shots. I was very pleased overall, and super excited to get the chance to try out the prototypes. Thanks for sending those protos out Titleist!
