We had a thread in 2002 when that change of TRHB was implemented. I remember the thread had contributions of photos from across history dating back to early 1900s of how TRHB appeared. Of course, the only record we have of how it played are oral history from the players across the decades.
But, a good historical understanding can be had of TRHB from the oral and photographic evidence we have. That is not even to mention the historical perspectives of the long tradition of caddies on TOC, who are among the real most credible witnesses we have to offer perspective.
In my lifetime, I felt the most representative example of how the ideal TOC could be presented, and played was the Tiger win of 2000. It played so firm - dust and nearly sparks resulted from iron shots off the turf. And, in a tournament where the greatest player, arguably at his lifetime peak, never once was in any bunker hazard the whole tournament, and his closest still in the hunt competitor was foiled in a RHB tragedy at the penultimate hole, demonstrated all the glory and essence of TOC.
In my view, that sort of historical evidence should be strongly considered and a consensus of all parties of standing, before any alteration of the field of play from the cradle of the game, should take place. If TRHB needs to be altered to preserve it, in a form that can be demonstrated to reflect its historical values and design, then fine. But, where is there any evidence that said process took place?
