I did a Bridgestone Golf ball fitting on an outdoor LM and they compared my current ball to their line to determine the best ball for me with my driver. They found the ProV1X was the best ball for my game. I'll give them credit, at least they were honest. :)
I've played the ProV1X since the ball made its debut, and despite testing other golf balls, there is no other better all around ball in the game. As a volunteer at the range of a PGA Tour event, I can tell you that it takes money for players to use any other ball.
