Shawn, your pattern sounds like a "wooless" woolly bugger. Good leach/dragonfly nymph imitation, or crayfish in the right colors. Here's another:
Hook: wide-gap bass hook, size 6 - 10;
Tail: four long Schlappen (or long saddle) hackles, your choice of color (black, grizzly, olive, purple, etc.), tied about 3-4" long, with a Krystal Flash/Flashabou topping of 10-15 strands, either to match or to brighten (silver, gold, etc.);
Ribbing: fine gold or silver wire, or tinsel, etc. for counter-wrapping palmered hackle;
Body: chenille to match tail color, wound neatly up the hook shank;
Hackle: long, webby saddle hackle (or Schlappen) to match, tied in at the front and palmered back to make a nice tapered silhouette, then counter-wrapped by ribbing, which is tied down at head of fly;
Eyes: large bead-chain (for shallower waters) or 1/32-1/16-oz. dumbells (for deeper waters), color of your choice, tied on top of the hook.
This will strongly resemble a plastic worm under water! Fish it the same ways - twitch it, jerk it, swim it, undulate it, etc. The point will ride upward so it can be (carefully) crawled over obstacles - or make it weedless by tying in a loop of 30-lb. monofilament!
Yes, bass may not be as selective as trout, but they can be selective at times, and the right combination of color and movement can set them off. My question is, since northern MI is crawling with brown trout that love to come out after dark, especially the big ones, has anyone here thrown any bass flies at them? The guys at the Alphorn Sports Shop in Gaylord, MI used to tell me to take big Marabou Muddlers out in the wee hours, throw them upstream as "dries", and when they drift downstream bring them bakc in a streamers. Then, false-cast enough to shake off most of the water, and repeat the above. I never did do this, but since Marabou Muddlers make great bass flies, it seems that other large morsels might be attacked by the multi-pound big dudes that cruise in the dead of night. This coming summer I'll have to check it out. And maybe for steelhead? I got a 9-10 weight...
No matter how big the one you just caught is, there's always a bigger one out there somewhere...
