THN (Tungsten Hydropsyche Nymph)

A fly I use a lot, is the Hydropsyche nymph. It’s a nymph that lives in most of our rivers. So, a must have in every nymph box. I usually tie a Czech-nymph style fly for this purpose.
I wanted to tie something different for next season. A fast tie. I came up with the THN, or “Tungsten Hydropsyche Nymph”.
