It is always blatant cheating to rack any other way than to....:
‘Place the head ball space directly over the footspot, lower and pull the triangle (3rd side parallel to the footrail) rearward until contacting the front pair while simultaneously forcing the remaining balls forward until all are touching’. That is the position the triangle is required to be in when the pencil line is drawn.
I think some confusion might exist with indelible lines that remain on tables where their original triangles have gone missing, and been replaced with larger models. Thus my earlier comment re: how a pencil line might not always be considered an official demarcation, but rather merely a guide. The VENERABLE rules of the game are very simple, regardless of what model triangle is available:
IF THE BALLS CANNOT BE RACKED IN THE PROSCRIBED MANNER (see above) BY LOWERING THE TRIANGLE STRAIGHT DOWN WITHOUT DISTURBING THE 15TH BALL......THEN IT GOES ON THE HEADSPOT! It either interferes, or it doesn’t (not complicated)! Any arguing, whining, calling over 3rd parties, or marking/moving the breakball, is demonstrating (IMHO) just as silly a form of behavior as those who constantly argue with the referee in ANY sport, thus revealing their LACK of sportsmanship!
So, I guess this would mean that those who play on all-Diamond equipment had better learn to select their behind-the-rack breakshots closer to the footrail!
