After you've tied all of the above suggestions Try tying the largest wolly bugger you can. It should be olive and at least 4-5 inches long. A 1/0 streamer hook works good. You'll need a little weight, I prefer led wrapped in the middle of the hook, just enough to get it to sink slowly. I don't like putting flash on this one, just keep it natural.

If you need to work it deep put a small split shot up half way on the leader, this way the bugger will dance. I hate buggers that are too heavy, it makes it harder to finess it.

Big bass like big flies so make sure you have enough tippet to handle the big boys.

Good Luck
