In the newest issue of Golf Digest, Deane Beman postulates that what is needed is a ball that spins more, as Tom Paul has been advocating here. Beman's point is that there have always been big strong guys who could hit it a mile; it's just that now they are able to swing from the heels on every shot because they KNOW that the ball will not curve disasterously as in days of yore.
In other words, the distance gains on tour are a function of low spin rates off the driver more than anything else. The ball goes long because the ball doesn't curve. The "rollback" that is so desired here by so many might be easier to accomplish through spin rates, as TEP has pointed out.
Interestingly, in the same issue, Johnny Miller points out that for the first time in golf history, the top 5 golfers in the world are all big men, over 6 feet. Miller mentions that height used to be considered something of a drawback in golf, and it may be that the ball has lessened the swing arc problems, allowing more powerful athletes to prosper.
