I learned a version of this technique from Bob last year, and I have since caught everything doing it, from the silvers, lots of kings, steelhead, and humpies. I never let mine hit the bottom, I just cast slightly above where I want the lure to be fishing, then twitch it real quick 2 or 3 times, then pause, then 2 times, then pause, again, and again. My jig is always in the middle of the water and you very rarely will snag a fish. I have most of the hook up right after the twitches, the bite is like a heavy pause, pull up, feel the fish, the ram it home. This is my number 1 way to go now, and I've had awsome luck in low and high water. It's all about the twitch. I also think that having it in the middle column of the water gets the fish that are active. I learned it all from Bob though.
