They effectively rolled the ball back for the 'rest of the world' in the early 1980s when they went from the 1.62 ball to 1.68. Barely anyone noticed and almost no one complained about the theoretical loss of distance.
way too logical of a post
Actually it took a bit more time than that. When I was in the UK in 1982-83, there were still many amateurs playing the small ball, but as it fell out of favor with better players, there was downward pressure to make it the "official" ball for local events and then club events, until peer pressure made everybody switch.
Also, it's interesting to note that in all the talk about the evils of "bifurcation", the governing bodies forget to mention that the Rules on the ball were different between the U.S. and the rest of the world for more than 50 years, and then when the R & A switched, the equipment rules were different for tournament players as opposed to amateurs for another 10+ years after that.
