Pay your money and take your chances... 

Early session at Armidilla II and had a good shot nice series for me (641)..   Late session at Alpha for singles and doubles, lanes were dry to start with and got worse.  Shot worst series in over a year  for singles and slightly better for doubles after I went solely with my plastic "ten pin" ball.  That ball was hooking substantially more than my Black Widow does on normal lanes. 

In a tournament like this they should at least give everyone the same chance.  The lanes should be run between sessions so that later sessions have the same shot.

Good Luck to everyone!
