For everybody wondering about the patterns to be used, here is some info from bowl.com.
"Four different lane conditions will be used at the Team USA Trials. One will be the USBC Masters pattern while the other three will be based on the Shark, Viper and Cheetah patterns used on the Denny's PBA Tour.*
*Note: The volume of oil and length of the patterns are to be determined and should be available on this site Dec. 20."
