Burns,
I've had some success with a Wooly Worm in some Texas Tanks with bream and crappie. I've never had any luck with them trying to catch trout. I prefer a cousin on the Wooly Worm known as the Crackleback for trout. I feel that it mimics more than one form of aquatic life: worm, midges, even emergers of mayflies and caddis. I fish is as a dry fly and at the end or the drift I strip it in. It catches fish pretty consistantly with both methods. This of course is just my opinion. Very easy to tie as well. Here is a link to the pattern:

I hope this helps.
Tight Lines,
