Sean - perhaps I've not stated it clearly enough. Let me try again. Maybe you dismiss my line of reasoning, or maybe I've not expressed it appropriately. We will see.
100% rollback aims to address many issues including safety / boundary problems at the amateur level, and is likely a more palatable form of regulatory review for manufacturers. It deals with the potential problems of next generation being longer than this one. In my mind - universal rollback is accompanied by a shortening of the course, likely leading to less inputs (chemicals, maintenance hours and most importantly water), likely lower cost and possibly faster rounds. I think it would be good for the entire scale of the game to shrink. It is simply too bloated, big and costly.
Bifurcation sees no impact upon long hitting amateur and recreational players, and the safety / liability issues they invite. The next generation will be bigger, stronger and longer, and will create a more pressing issue. Bifurcation may also be a less palatable approach to manufacturers, and importantly, is contrary to the wishes of the game's governing bodies who have expressly stated a wish to retain the one set of rules for all. Bifurcation divorces the pro game from the amateur game even further than it already is.
There have been sharp minds in the game suggesting that the flight of the ball should be limited, for a century. Expressing concern with distance. MacKenzie, Behr, Crump, Tillinghast, Flynn, Longhurst, Doak, Nicklaus, Player, Palmer, Crenshaw, Faldo, Woods, Clayton, Shackelford and many, many others. Heck - Chamblee is now on the same page. Are they all wrong? Who else would you like to echo those words? At what point do you think this cohort might have a valid suggestion? And to those who refute the need for a rollback - what makes you think you know better than these people?
Also - nice points on the perils of implementing bifurcated rules Thomas. That is a more complex path than universal rollback.
