I'd love to see some results, looking forward to it. I've experimented quite a bit with different brands for my own game. I've been surprised to find that while I give up some distance, I actually really find a slightly softer ball much, much easier to control. I love the feel of the ball 'sticking to the face' through impact. Compression.
Take for example the old top flight xl (or even the original 'tour ediion'). Certainly a fairly 'hot' ball. Compared to the newer top flight 'feel' ball.
At least for my game, there is simply no comparison, the 'feel' ball, while a 'softer' ball, gives me much, much more control. At the very least, much more feedback.
There is little doubt at all that the ball of today is far better than the ball of just a few years ago. I notice this most on windy days. A 'high spin' ball of 5-10 years ago would play great on a calm day, but upshoot in heavy wind. Most balls today can handle cutting through the wind without such extreme upshoot, if any. Of course how much a ball is influenced by the wind is also a matter of how well it compresses (just like throwing a frisbee - lots of spin, as a general rule, equals more control).

There is much more to the performance of a golf ball than the "compression" of the ball. There is spin, trajectory and aerodynamics. In the hands of a better player, the "feel" factor and spin ratios become beyond important, they become required. If a Top-Flite XL performed the "bounce test" with the most success, then why did the tour players play a wound ball? Fred Couples and many were using the Professional 90's instead of the 100's. This was due to spin, feel, and performance.
Today's ball is completely different (Pro V's) Slightly harder in feel, yet spins plenty and fly's better than ever.
Yet, most practice balls or range balls are Top-Flite or Pinnicles due to the hard as rock feel and durability ..... not performance. Did Lee Trevino really win with Top-Flites?
The next time I'm about to spine align a shaft, I will consider spining it according to the center of gravity of the club. In laymans terms: Letting the clubhead hanging straight down on the shaft and aligning the spine vertically - along the gravity plane.
