To me, a maribou leech and a wooley bugger with body hackle are very similar patterns, and I fish them the same.
After casting, I use a series of short strips, wait a few seconds, and then repeat. Also, I've had success with just twitching the rod to indicate some movement. It depends upon the type of water that I'm fishing at the time. If the water is fairly swift, I'll use some weight or use a bead head WB to get near the bottom.
Sometimes, I'll try a continuous upstream retrieve, and I've had some 'bows just nail it hard. I assume that the bugger going past their nose intices them to strike.
