So the parameters to consider are:
- weight - the fly needs to sink fast enough to reach the part of the
- water column fish are feeding
- looks similar to the very in size and shape
- behave similar
A lot of thoughts - but do not worry - the solution can be extremely simple. The tricky bit is to find the balance between "sink rate" and "natural behavior". One main concern is that you know what you have at the end of your line. You, the angler needs to "be with the fly at the end of your leader". That for me is the essence of flyfishing, might it be dry-, streamer- or nymph-fishing. Dead drift nymph fishing is maybe the toughest bit. It takes a lot of imagination. The funny bit is that tying the flies - even the simplest ones - yourself. The time you invest pays off. You "know" that bug at the end of the leader. Don´t laugh please, but it feels like the thing speaks to you through the line.
So the simplest way of getting weight to a fly is using a small metal bead. Such beads come in copper, lead or tungsten. Tungsten is the ideal material in my view as it has the highest density (weight/size ratio). So you get away with a rather small bead and still add good weight to the fly.
If you want to be fancy you can add colored beads and even this e which are formed like real insect heads. Pretty cool, but honestly catches more fishermen than fish. The prime aspect is to wiggle the nymph in front (and not above) the fish.
Here is a little Step - by step on a simple bead head nymph. Please modify to your liking - just don´t overdress it - less is more.
