I was a bit skeptical at first, every ball company has their own way of fitting. But at our Member Guest a few weeks ago Titleist did a demo day and included a ball fitting. And the first recommendation for me was the Pro v1x (been playing the Pro V1) and bada bing I am as happy as a clam with the switch. I find them a bit longer and I can still get them to the stick. I think as usual Titleist is just a step ahead of the rest and have the fitting down.
