I am still for reeling back the ball. Top Filtes are sold for basically $1 at many locations. So a ball can be sold at retail for $1, for presumably a profit by the retailer. That includes presumably some profit for the manufacturer as well after material, manufacturer, advertisements, R&D, etc.
And the Top Flites are very similar, overall, to the top line balls.
In the end, it will not just be about the winning score, or tournaments, it will be about how short your course plays for high school kids.
Those new young members will tire of hitting driver, 8 or 9 iron, and move on to a tougher course. Or they stay at your course and want to lengthen it, toughen the course as they age and come to head committees, Boards, and such. Scores or course records might eventually be a tipping point, but only at a few courses. All these future course changes (lengthening) will continue as guys that are only near scratch just get tired of hitting wedges.
The issue can be approached in several ways, or combination of ways, such as a lighter ball, or have minimum spin rates, etc.
Until the manufacturers have no money for R&D, the ball will come to go further either ever so gradually, or in a few spurts, as learning about materials, compositions, shells, covers, etc. continues. And realistically, players will grow slightly taller, stronger, etc.
Everything really points to the ball, practically the lowest cost item of any golfing year except for maybe tees.
