Streamers are SUCH Fun! I obviously don't have to tell you that.
As to patterns, I am not all that sure it matters much. How is more important than what. But...here are a few that stood the test of time for me:
The most effective, or the ones I had most confidence in, were the top four. I dubbed them (l to r): "Chub", "Lightning", "Thunder-n-Lightning" (tied in tangerine/white or chartreuse.white), and "Tangerine-n-White" (hardly a name but a simple description). That T-n-W was uniquely effective as it sometimes took fish after passes through with other patterns. Eventually, it was all I tied on.
The streamers were tied on #2 or #4 (where stream trout existed so I wouldn't puncture eyes on smaller fish) 6xl hooks. The wet flies (don't over look them) were tied on #8 black salmon hooks.
Important components:
-Bucktail pulled a meaty wake (as did the chenille used for the "Chub" body).
-Fluorescent colors. Although I was apt to use "Chub" in clearer water.
-Mylar for flash, which I eventually incorporated alone to make "Lightning" which literally flashed like a little strobe when I pulsed the rod. It worked really well in roiled water, shade, and low light. It was too much in bright sun and clear water.
