I fish a dry/nymph combo most of the time and I use Tungsten bead head nymphs quite a bit. I use a Foam beetle or a Madam X sometimes but mostly I use an Elk hair caddis, great fly, easy to see and floats well. Many of our streams are quite deep and I might go as far as 8 to 10 feet between the dry and the nymph or in a riffle it might only be 2 feet.All the best.Mike
