AK Best's Quill Bodied Dry Flys..What do you think ...
My biggest fly caught trout: 31", 10-lb rainbow, #16 tan cdc hatching midge (thread to suggest segmentation), 5x.
In a stream: 24" Henry's Fork Rainbow, #18 greased pheasant tail (wire rib+fiber orientation = segmentation?), 6x.
I've caught more 18" and larger trout on #18 - #20 bwo's, tricos and midges in Washington State than I can even begin to recount... way, way more than any other fly patterns, sizes. Then again, the only time I am fishing something big is when I can't fish something small.
For instance, just Saturday I was at Pass, probing, stripping... big stuff. Seems everybody has their depth probing, shore probing operations going, too, and I didn't see a bent rod the first couple hours. Fortunately, there were chironomids popping in good numbers in prevailingly calm, moist conditions, and soon the 18-24inchers joined in on the easy pickings. I had no misunderstandings about the word "switch", as in, "switch to the floater", at the mere initial hint of an impending event.
Then again, the only time I am fishing something big is when I can't fish something small.
Oh yeah.... biggest Rocky Ford (have a hard time classifying it as a "stream") fish: 28", #18 tan palomino midge (not segmented at all) at the feet of an approaching Encroacher (at Rocky Ford, of course)!
Maybe the best fly is the one you can actually make a meaningful presentation with because somebody hasn't just put all your fish down (for you).
