Be careful not to touch the bulb as the tubing will melt. When putting your fly rod sections together start them at a 90 degree angle and slowly twist the section on and in until the guides line up. This will preclude most breaks at or near the ferrules, give better support and making disassembly much easier. We are often asked by beginning fly fishermen what trout flies should they buy to get started. It would not hurt to carry some in 18 and 20.
Streamer patterns vary greatly from region to region and by body of water - lake vs stream, etc.
When a mayfly emerges on the waters' surface, it floats a while till its wings are dry enough to fly. This gives the predator time to stalk the fly. It can carefully watch the fly's behavior and give it the tail flip if it is not happy with what it sees. On the other hand, caddis flies emerge to flight the moment they hit the waters surface. The knowing trout will not hesitate to nail a caddis pattern very quickly once it is seen, for the fish knows it has no time to consider its actions.
