I was farting around with these fine round rubber legs that were given to me by a manufacturer to try out this past winter, and decided to incorporate them into my Caribou Caddis adult. Since then, I've had numerous occasions to try it out and the results so far tell me the trout like it.
Whether they take it as a caddis or cranefly I don't know, and really don't care, but it works during the day and at dusk. Maybe it just looks "fishy". Maybe it looks like something the trout have never seen and they just want to see how it tastes. Maybe it looks so ugly to them, they just want to smash it, and knock it dead like Obama's fly swatting trick. (At least we know there is one thing the guy can finish......)
Will it stand the test of time? Odds are that it won't. Many newly tied flies work well "off the truck", but few continue to work season after season, so we'll just have to keep fishing the darn thing and get back to you in a few years. My Caribou Caddis w/o the legs sure has passed the test, so who knows?
Give it shot if you're a tier, or wait until it hits the big box stores. I'll keep you posted.
I have to come up with a new sign-off.........some appliance company stole the old one ; )
