well sounds like you are on the right track. first advice, your line set up will work, however i would recomend upgrading to at least 10 or 12 lb mainline, doesn't have to be anything fancy. do the same thing you were doing and run the test on your leader a little less than your mainline. that steelhead worm should work for steelhead and trout, i personally drift fish them and get a ton of fish to bite that thing. Eggs work, shrimp works and maribou jigs work. I think fishing with a bobber like you are doing is a very effective method of fishing. I think you might be fishing in a bad spot or something so I gonna have to ask where you are fishing at? The best advice someone gave me when i was learning was to go fish at McIver Park on the clackamas, although you are a little late for steelhead and chinook. Try to find places were other people are fishing, and watch them, study what they are using, where they are casting and try to deduce why they are casting where they are, why there are using what they are. Read any books you can find as these will answer pretty much all questions you have regarding tackle and rigging. Learn the runs of fish that come through the clackamas. Get some eggs, and head over to Oxbow on the sandy and try and catch a coho anytime this month or the next should be good, just watch what everyone else is doing and copy lol. Write down were you fished, when you fished, what time, weather, water conditions, water level even if you dont catch anything and refer to your notes as a what not to do if you dont catch anything (all these things make a difference between catching and not catching). Hire a guide and go out and catch a few big fish to remind yourself that its all about having fun and what you are trying to learn how to do. These are just things I figured out after a couple years of fishing.
