The Action Jackson is the most successful articulated streamer pattern that I have ever fished. I am using an AFF MP001 (up-turned eye, multipurpose, stinger hook) for the trailing hook and an AFF S404 (straight eye, 4X-long, round bend, streamer hook) for the front hook. Check them out at http://www.allenflyfishing.com.
There are three things that make this pattern so effective. First, most fish do not fully eat a leach, sculpins or bait fish on the first strike; they wound them first by biting their tail. The stinger hook at the tail of the fly reduces the chances of short strikes/ missed opportunities. Secondly, the articulated portion of the tail moves freely in the water and gives the illusion of a swimming leech, sculpin or baitfish. Lastly, the squirrel hair and legs provide excellent movement in the water. The sili legs project lots of UV light that grabs the fish's attention. This pattern is also effective in the following colors; black, rust, chartreuse, brown, tan and natural. You can also tie this pattern in different lengths.
