This absolutely makes a big difference and what you are seeing is real. I recently did a virtual ball fitting with Titleist and switched to the ProV1X Left Dash. It has all the same characteristics as the X, but with lower spin. My course has all raised greens, many of which have false fronts. I hit the ball with a lot of spin and playing the X, I often hit a shot to the middle of the green, only to have it spin back off the green. I tried a sleeve of left dash and the results were amazing. Just ordered a bunch during Titleist’s promo. Here is a link to the review of left dash.
