Nice, Gary,
Black Bear Green Butt--that will bring back some memories from those who used to fish the Bangor Salmon Pool. Sadly, by the time I moved back to Maine and might have fished there, the salmon run was in such poor shape I didn't feel right about trying to stick a hook in one, and the Maine fishery has been completely closed for many years now.
I do love my bucktails for striper fishing. My go to flies are a bucktail Ray's Fly, and several variations on Joe Brooks blondes. Strangely, I almost never fish bucktails for trout, though I do a lot of streamer fishing.
I have a buddy who swears by "the original" Art Fllick blacknose dace: brown phase "black bear" over black bear over polar bear.
