the pattern wont change for shield, this pattern is some what of ditch but, the brake down off the pattern will determine, the winners and losers, as one the weather is different everyday up here, and will have a big affect on the pattern, and there is nothing wrong with the phoenix, as it is perfect working order,
i think you will see some big scores, but pin carry up here is very cruel, i know it has cost me at least 3 perfect games already.
and also TBAL sets the pattern not the center, so don't go blame the center, and the better and inform bowlers will always ride to the top, generally.
i say to all, wait until end of day 2 of sheild to determine, the quality of the pattern given
