I use wooley worms for steelhead in the early spring as the ice is going out. I drift them on the bottom in the current and they can't be beat for that application. I hit steelhead up to 20 lbs or so on them. I can't speak for how they work at other times of the year. I use them with spinning rod also, drifting the wooly worm about five feet ahead of a light pencil sinker in the current.

We use the worm and bugger a lot sucessfully for several reasons. Normally a larger size 6, 8, or 10 is selected so as to combat the ever blowing wind more easily plus provide additional casting accuracy and distance. In so far as color black and olive seem to be the most assuring choices. For various species of trout in river and rocky creek fishing I have as good luck with these two as anything else, maybe better.

Great fly for trout. Don't leave home without them.

Probably one of the best most common streamers, you can use it in streams and lakes and it works.
