again, technically, a woolly bugger is classified as a lure.
I'm not real big on flies, I'm more on technique. Fly fishing 40 years, I've pared my fly choices down to a handful.
Coldwater, I'll usually fish first with a floating line, sometimes dead drifting with an indicator, but more often dead drift and swing without an indicator.
I know every BWO and caddish hatch in 8 miles of my tailwater, and go out of my way to fish them.
In warmwater, I fish 3 flies always with a Teeny line.
I always bring a floating line and sliders, but most often don't use this
This particular morning we could see big bass moving out of a huge deep hole to feed on a shelf, so switched to floating line with slider to move down and ambush them - usually here we're on the shelf and fishing into the hole with a Teeny line, counting down before we strip.
Always in coldwater, I also bring a Teeny line. There are some places I'll rig it first. I use the same 3 flies as warmwater, and also add soft hackle wet flies.
In wide spots with chert bottom in the tailwater, I'll use my creeping bottom bounce with a whistler or cats whisker - places I'm more apt to drag up a leaf rather than hang a rock.
A common technique with the Teeny to get down close is cast up and high stick, dead drifting to get down, then swing. The target water is the swing, but the high stick can still take fish on the dead drift. I've caught some honking carp with a cats whisker on the dead drift, rainbows and bass as well.
But the choice for the Teeny in coldwater is across, drift to get down and swing, or just down and across swings.
This big hole after the tailout at Rockytop is a great place to fish streamers straight down the current - shoot for those rocks on the far bank - what you don't see is a creek mouth on the right - if I fish this hole, I will rig the Teeny I brought along (otherwise, I'll make the bend to the next chute and BWO hatch)
tailwater piggie as I described just above
here's my buddy Ewell with another piggie at the tailout of the same hole (left of the photo above)
BTW, sight-fishing in clear water on flagstone bottom, you really see the result of bottom bouncing - the fly makes a mud ball along the bottom. i've seen big bass chasing the fly and pounding the side of their head on the bottom, strike after strike on the mudball.
