This is a side conversation that developed on Gene's "Secret Fly" thread... I think that adding a "hot spot" to any fly is worthwhile. I first ran across this while I lived in the UK where they added bright florescent colors to pretty much anything...nymphs, scuds, clousers, baitfish, etc. I no longer think that bright colors are reserved for steelhead. You can add a hot spot to the tail, head, body or to all three. From what I've seen, the amount of color is only dictated by water conditions and the agressiveness of the fish. Flies that are now gaining popularity here in the states such as a posting here recently of the Kreelex or similar "sparkler" or "blob" flies tied with an overabundance of flash, that are quite common in the flyboxes on the stillwaters in England, attest to that. When I fished in SD I had a underwater camera and learned quite a bit about fish behavior and more often than not ended up with something with floro green on one lake. Five miles down the road, they liked orange and I would do dismal on green. My first year fishing salmon hard and it's all about color. I guess my point is, don't be afraid to add some color to your flies, you may just find that it increases your productivity. Below are some of the flies I've tied over the years that have hot spots and brightness.
