DaddyO,
I have fished some articulated stuff at night. I have had some success this summer on it, especiallly on circus peanuts. I also had a monster smash and missed hook up on a mufasa at the very beginning of summer at night. At night I don't do a whole lot of stripping flies unless its just back to me. I swing pretty much all of my flies and the ones that present a "jiggy" motion have caught more fish for me this summer.
I have caught less fish than if I was fishing smaller flies in the 8-12 range but ALL of them have been decent fish, the smallest of which was a chunky 16 incher, and a male rainbow that had to be a solid 23 or so, one of those fish that actually got put on the reel.
