Well, I think this theme has just about run its course, I'll finish with a flourish of three more variations.
The first one is a variation on my rootbeer bugger. It has an orange glass beadhead. The orange could look like an egg, or just a shiny attractant that flows with the other colors of the fly. I like the glass beads for some of our shallower streams. It sinks the fly, but not as deep as brass or tungsten, so it won't get hung-up as much. If it isn't getting deep enough, just add a pinch of tunsten putty.
The second fly is my yellow/olive WB with a green glass bead. Gives a little flash and will sink the fly gradually.
The last one is the old standby olive WB with an olive glass beadhead. Nothing spectacular, but maybe just that little bit of distinction that will trigger a strike.
What variationsdo you tie?
