I wouldn't pass up a good pool at night without a bomber on my rod. Small field mice are all over the place out there: I've even had the little buggers crawl into my sleeping bag with me when elk hunting.
The big browns never seemed to get really active for probably 2 hours after complete darkness. The small fish would shut off just after dusk, then nothing would happen for quite a while, then the big ones would come out.
I don't think they were very active on the full moon, but I can't really remember. I do remember casting to the sounds of boils not the sight of them. Even then, I started where I thought I would be short and worked long when casting.
Although I was literally "blind casting" I would stand and wait for a long time listening for fish rather than just start throwing randomly. I also rigged up well before getting to the river, and used no lights till I had a fish up to the bank. The place I fished was a cow pasture (in those days) with thick wet topsoil that would jiggled a little if you tromped around on it, so I walked very softly.
An old guy in Maine that my dad and I rabbit hunted with 3 days a week took me fishing a few times in little brooks and taught me about walking and stealth. I had never fished north of Daytona beach before. He used a 20 foot telescoping fiberglass pole with 4 feet of mono tied to the end. He'd stick an angle worm (not a night crawler) on the hook, stretch the line back tight, stick the worm to the top side of the rod with a little spit, and thread it through the alders till it was over the water.
Then he'd rotate the rod 180 degrees so the worm was now on the bottom side of the rod, tap the butt and the worm would fall in the water. That guy caught fish that no one else could even get to in deep narrow brooks running through alders in swampy areas. He'd start sneaking up thirty yards away from the alders.
So I try to walk softly, always, and am always amazed why guys clomp and thud along the bank then talk in a whisper after they've driven all the feeding fish back into the undercuts.
Anyhow, I think you really ought to give a bomber a try a number of times. In slow moving water, you'd be surprised how much you can hear just standing there quietly. And if you get one, he'll likely be a good one.

That looks like a 32" fish in your avatar. How come I don't see a fly line out there?
