Floater-Diver (thin)
Note: Definitely not tied to match a hatch. As I was working my way into fly fishing, I had pretty much gone to fishing with an ultra-light spinning outfit. One of my most effective lures was a 1 1/2 inch long Rapala in various colors. This is my attempt to replicate it. Tail is marabou, then you wrap some white foam on top of the shank. Take a piece to the tubing. I use a pair of needle nose pliers to stretch about an inch of the tubing. Then I will mix a bit of 5 minute epoxy, and coat the stretched area. Then I will squeeze it together to form the lip and bend it down to form an angle. When it dries I trim it to shape. I will add color to the foam with permanent markers. Then I slide the tubing over the hook shank, forcing the eye of the hook through the tubing above the "lip". Then I wrap down the tubing with clear mono at the back of the hook. When using Corsair tubing, I usually coat the tubing with a fabric paint that dries fairly clear and has some sparkle in it. Once that dries I'll add additional color with the permanent marker, add the eyes then coat lightly with epoxy.
After several experiments, I got the width of the lip right and the fly actually did what it was suppose to float, then dive and wiggle when stripped in. It was not as effective as the Rapala, mainly because of the single hook. I got a chance one day to hold it in the current and watch some little smallmouth attack it. They all hit it from the side just behind the eye (where there's a set of treble hooks on the lure). I did catch a few sunfish on it, but eventually lost my best one to a snag on the bottom.
