Can't go wrong with egg suckers, try red head and black body. For rivers I like to use a bead head, it helps it wiggle as it swings though the current, deadly. For fresh water try tying a balanced leach. Look into some of Phil Rowley and Brian Chan's stuff, thay have lots of info books, how too DVDs, great for boosting the learning curve. Dark carey special even works, and will be a great fly if caddis start poping. happy tying!
