Boss,
Its really not that bad.
I tie something very similar and the ones I fish with take about 20 minutes. I know it's a lot of time for a fly, but it is what it is.
I have enough flies that I tie just to tie; for the art of it.
If I were to tie my stonefly nymph for a competition I would spend around an hour on it.
It's really a simple pattern, just many steps.
