Fish Assassin is correct...bottom bouncing with a short leader is a legitimate angling method. It was a technique that was more common in the US. Most of the anglers south of the border often used short rods, level wind reels, short leaders, & bottom bounced Corkies, Spin-N-Glos, etc... which kept the hook off the bottom. Canadians on the other hand prefer long rods in the 10-11 ft. range, level winds or center pin reels (originated in England), & float fish.
Bottom bouncing/flossing was something that originated on the Fraser when it opened for sockeye & seems to be a "technique" that has moved over to other rivers. I have fished in the Lower Mainland for over 40 yrs. & have worked for DFO. I am surprised to see how many angler do not realize that the currents actually lift their hooks on long leaders near the surface. These anglers do not seem to realize why they are not catching many fish. You will catch more fish in the mouth with a shorter leader if you let the wool, bait, etc.. drift naturally.
Glad to hear you "want to avoid anything that might be considered unethical." Send me a PM if you have any questions.
