Chris - I talked with Pat Fleming a year ago about the Nine-Ball break. He said that the break was a huge advantage on regular equipment but then the pros began playing on the pro-cut pocket Diamonds. The break advantage was virtually wiped out. You are on the money.
I respectfully disagree about the importance of pattern racking. On regular equipment (most of the equipment) where top players are concerned, every little thing matters. The slightest advantage can make a winner. Most people do not understand a good pattern racking strategy. A good strategist never pattern racks untill it matters. He may random rack an entire set and then pattern rack the hill-hill game. He won't be questioned.
You are right that for 90% of the players, it is not important because they cannot get out anyway.
If he waits until the Hill-Hill game, how do you prove it is Pattern racking. If it is such an advantage why would someone wait until "HE" is racking for the other guy and let it get Hill_Hill. Sounds like shutting the gate after the horse got loose.
I think this sounds what I call the Hillbilly syndrome,,,worrying about everything except playing pool
