The issue that nobody has really addressed here is that the spin rates for ProV generation balls are very low off the driver only, allowing elite players who know that contact will be relatively square to swing out of their shoes. THAT is what has made the game more boring, I think.
The issue really isn't about curving the ball off irons and wedges; that can still be done with the modern ball. I don't think it curves like an old balata ball, but it curves enough to allow/cause shots off irons to curve. If anything, though, it takes MORE talent to work the ball now, since the spin rates are lower overall.
But as someone pointed out earlier in the thread, to curve the ProV off a driver would require much lower swing speeds to maintain control, and therein lies the future; minimum spin rates off the driver coordinated to the wedge spin rates, so that if the guys who want high spin balls for shots around the green, they're going to have to hit a high-spin ball off the driver as well. The high handicappers who want distance could still get it with low-spin balls. Much better than a "roll back"...
I believe this will happen.
