Yeah trout, Olive willy is a good one. I have quiet a few of those. My buddy was doing good one trip with something he was calling a calico bugger. Sounds similar to what @Stonedfish is talking about. After that trip he was searching high and low for some of that long out of production...
What's the one fly that has accounted for them most fish in lakes for you? Pictures for bonus points. Sometimes I spun out and can't decide what pattern to tie. Mine is a seal bugger.
