This is not quantitative mathematics. This is not string theory. This is not "Who Shot J.R.?" This is a fishing Pythagorean Theory; Egg hook + brightly colored yarn = steelhead. This is fly fishing inverse proportional value at its' best. There is no greater bang for your buck. One minute of tying a fly to catch a thirty inch fish. What other fly can you tie in less time that gives such a pay off?
Despite their simplicity, Glo Bugs just plain work. I've seen steelhead dart across pools to slash at glo bugs like a pike hammering through a school of shiners. My favorite yarn is the Glo-Bugs brand micro yarn. The most effective color for me has always been baby pink with a bit of champagne mixed in for a little color variance. I've also had success with flame, apricot, and light roe. I've always wanted Oregon cheese to be successful just so I could drop the inventive name, but steelhead in my area are very partial to pinks, oranges, and reds. I can sit down at the vise and rip out a season's worth of eggs in an hour. They don't need to be perfectly tied, and you can break up fly tying monotony with bright and creative color mixes.
