As far as catching while drifting. Here in my home stream (Clack) I ususally find that at the far end of a drift you will either feel it stop like it is snagged and then you would drive the hook home, or in the middle of a drift you will feel a short tug and then some head shakes and sharp movement (hatchery steelhead) or perhaps a suspicious stop and then a run like a bull (nooks and trophy steel). As far as spinners are concerned, its an entirely different mindset that you have to get into. You MUST learn to read water correctly to catch them on spinners or you might as well cast into your bathtub. You want to hug then bottom and present the spinner as slow as you can while keeping the blade moving. If the blade isn't moving, you aren't fishing. If you don't feel the blade tap a rock here and there, you aren't fishing. Lastly, if you aren't losing at least SOME gear as a beginner...you aren't fishing the spinner right. Read the book by Jed Davis "Spinners for steelhead, salmon, and trout". It was the book that inspired me to learn the complex art of spinner fishing. I read the book and the next week I was into my first nook. It was awesome. They hit a spinner like it called their mom a nasty name...An unmistakable bite. If you miss the strike then you arent paying ANY attention. Good luck!
