Edit: I should have read your post closer. 9 foot tables eh? Depends how faryou want to travel. Dr. Cues in Seattle has a few weeklys. Not sure about Portland for 9 footers, I have only played at Classic Billiards and not sure if they have tourneys.
Not sure how much you get into Vancouver, or Oregon City, OR. KCs Midway has very good strong shooter tourneys many days a week.
Also in Vancouver, Halftime gets many of the same players. Pat Schumacher, Glenn Atwell, Mike Stevens to name a few. Tim Tweedel has also move to the Vancouver area and may be seen from time to time. Strong player.
The only 9' 8ball tournaments I know of are at Uncle Jacks (formerly The Breaking Point) in Lynnwood on Sundays at 5 with IPT rules. Races to 2 or 3, 3 in the finals.
Raul won the last one (we weren't there, this is coming from Raul). He ran a 3 pack on Dan Louie in the last Finals.
