Lou, eliminate the "besides" and you can answer your own question. Just imagine how the better teams in baseball would fare if they played 15 innings instead of 9.
However, 9 ball banks helps a guy with a strong 9 ball break. Full rack is usually played off of a safe break (thats how Bugs and Taylor broke full rack, so that should end that argument). The best banker should play full rack. A strong shot maker can do ok at short rack because of the plethora of nice angle "naturals." The balls dont clog up, most of the pockets remain open, and the balls are all over the table.
Full rack, the pockets are often closed, the balls clogged, and most of the balls clustered on the foot of the table. Multiple rail and off angle banks are often the only shot. They require much more banking knowledge (english, speed, strange angles) than natural 2 to 1 angle shots that dominate the 9 ball rack.
In Chicago the game of choice is full rack. In Kentucky, Tenn. short rack is played much more. They like to shoot more down there. Their hero is Truman Hogue, an offensive genius. In Chicago the squeeze is the thing. I'd like to think that I was one of the poster boys for that suffocating style. Bugs was famed for off-angle freak banks, was very aggressive, but could play strong safety too.
The best player plays full rack, no question about it. Anybody can shit out playing short rack.
My guy, Riley Jet Johnson, is having trouble getting anybody to play full rack, but there is probably a boat load of short rackers that would have a big chance with him. I wouldnt bet your money on him playing short rack.
