If fishing double rigs like a lot of tend to do on the willamette. Run a barrel swivel up your line then a T bead below it, tie your normal setup for single rigs on. run the t bead up to where you want your second rig. Push a toothpick into the bead and attach your second leader to the barrel swivel with a snap. Work great keep your upper leader about as long or shorter than the distance to your lower rig to help avoid tangles when realing in. When fish hits the upper it slides down to the lower and you dont have a huge distance of leaders to try and reach a fish with the net. Also while sitting in the baot trolling get other rigs ready, spinners and other baits tied to a leader with snap swivel can be changed quickly. Experiment dont get stuck trying the same bait all day if they arent biting give the fish some options.
