Listening to a podcast that was comparing multiple urethane/tour balls across 3-4 OEMs, one tidbit caught my ear. With the robot swinging at 85 mph, the longest ball was the (2019) Pro-V1x. Due to the higher launch and spin, it carried longer than the other tour balls.
To me, that puts the argument needing the "speed" to hit a tour ball to rest. The X may be Bubba's ball, but it can be the ball for me at roughly 30 mph slower swing speed. They also find that softer balls will always have a slower ball speed than a firmer. In spite of the claims from at least 2 if not 3 other OEMs that lower speed players need a softer ball to compress it with driver.
As golfers we tend to focus on replacing drivers every 1-2 years but almost never get fit for balls. For the one piece of equipment used for 70+ strokes a round it makes sense to try more than 1 line with each release to find the best performance.
