Most ball manufactures are close to what may be the maximum distance as governed by the sport. Given this is correct, the next area that many companies are focusing on is feel. Since many golfers prefer a softer ball for better feel......this is what the ball manufactures are marketing and manufacturing to attempt to gain an edge on their competitors.

Thank you for that. Seems fairly logical.
I was talking to a friend and old team playing partner in our Pro Shop an hour or so ago and golf balls came up. The spin rate thing was raised by me in the conversation and Duncan told me that it was not all about stopping the ball with shots to the green, but more about keeping the ball in the air longer off the tee and ensuring that the ball did not soar and then just drop. That made a lot of sense to me rather than just reading about "spin rate" without a plausible explanation.

Strange how only one person managed to give me some sort of reply to my question re spin rate. His reply referred to feel rather than spin rate for some unusual reason!!!????? Seems that the golfing world must be up to speed with all the latest tech and I am being left in the lurch!! Seems that my question was answered by my old playing partner rather than a member of Team Titleist, which is a little disappointing.

Being a youngster and still learning the game at 70 I'll give this a try... There are differences in the trajectory that is more than just spin and feel. In the short game, the XVAVX for spin speeds. So trialing the balls starting there, this can impact your stopping power on the greens. The TrueSoft (2 piece surlyn ball) may spin as much as an X if you can't apply spin with your swing or the grooves on your 8 year old wedges are worn smooth. If you can control spin on approaching the green, then the X or V would be your best choice.

Off the tee, almost all balls are designed for low spin to work in combination with drivers released in the last 4 years. Using a McGregor persimmon driver, you may want to stick with balata balls. Independent of spin, the launch angle of the XVAVS off of driver. The distances will be comparable with all 3 with the resulting lower angle of descent as the launch is lowered equally more roll out. In most cases I get longer drives and long irons/hybrids with the lower descent angle with the AVX, and I get the same spin numbers off of X and AVX.

Whatever you learned in the days of the Pro 90 vs. the 100 is not useful anymore. With each release of Pro-V's, it will be worth doing a trial around the greens then off of the tee to decide the best for you. Short of getting a ball fitting should Titleist hold one near you. With advertising compression and swing speed as determinants from other ball vendors, you shouldn't use that as a guide. Before Titleist released amber balls, I trialed the amber Q-Star Pro. Lower compression for slower swing speeds. Fits me like a glove. Except off of driver I was getting a couple more degrees of launch and was losing distance to both the V and AVX due to the 2-3 yards of roll on landing. The dimple pattern was also designed to help launch the ball higher, so that glove didn't fit my hand. Even with a driver speed of just above 80 mph.
