2008 USBC Team USA Trials Medium
Team USA Trials
The 2008 USBC Team USA Trials Medium is a 39-foot pattern with moderate oil volume (23.5mL) and a 2.14:1 ratio that creates a distinctly playable yet challenging scoring environment. The forward-heavy oil distribution (9.36mL front, 14.12mL reverse) with 587 boards crossed promotes continuous lane transition and rewards precision, as ball motion develops gradually through the front end before reactive response in the backend. This pattern favors controlled, stroking styles with strong rev rates over aggressive throwing, as the moderate ratio prevents heavy dry boards from becoming too penal while still demanding accurate miss room and line management typical of a USBC Team USA Trials event.
