Did you draw your Rimrock permit out of the "Bull" category? I'm guessing probably so. If that's the case, you may still have points in the quality category. Best odds if you want to hunt bulls this year is apply for an archery or muzzleloader quality elk permit.
rimrock or little naches
If you want a chance at a branch bull hunt the west side. But I'd say hunt the same unit and re apply for the branch tag. Your best success will come from an area that you know well. Learn it, and stick with it, and it will pay off in the end.
