The problem is, there is no authority in pool powerful enough to dictate how rails should play. Even if the WPA said only a certain rail could be used, there would still be thousands of pool tournaments across the country that would simply use what's available and table manufacturers would comply if it were a good business decision to do so.
That said, competitors in many sports must endure changing environments. It's just par for the course. Runners think concrete is too hard. Baseball players think astroturf is too bouncy. Tennis players think grass isn't bouncy enough. Yet, some adapt. The best pool players are often very adaptable.
Of course,the most skilled will always prevail. The skills needed will be different, however. In fact the game itself will be changed into something unrecognizable. I'm of the opinion that the game itself has an intrinsic value that is worth protecting. Guess I'm conservative like that. And no, I'm not a pro, so I do find it somewhat challenging to adapt, especially in tournaments with no warmup allowed. (We have those here).
Pool does have a governing body, it's just that it's a worthless hunk of sh..that does nothing but collect money. The American chapter is especially pathetic.
