With fingers crossed behind my back.........I have no secrets....honest....I didn't do it...It was, ah, the volcano?....Locust?.....nah, that fly came in a box of Wheaties.....really, cross my heart and hope to die.....you don't want a fly like this....Trout laugh at it....no that's not a Whipperwill ear feather....plain variety garden sparrow....honest....Jungle Cock?....you gotta be kidding?....a kid could tie this fly....Polar Bear hair?....I wouldn't be caught dead using it.....honest. But in all honesty, I did find a very old box of Christmas ornaments in my grandparents basement that had some old tinsel that appears to be made of lead or a lead alloy. Great for weighting down sinking flies when wraped on the shank before other materials. Whew...that wasn't easy.
