I tie what I can't buy or anything that is too expensive
The only flies I tie are my preferred boatman patterns, and my articulated streamers/intruders
It sounds like you don't enjoy tying nymphs, so don't tie em.
From a technical standpoint, I think if you skip dries, you will be hindering your progression long term,
but I don't think it would hurt too much if you delayed getting into them tho. Plus quality hackles are expensive.
I think you can jump straight into tying streamers.
Tying in schlappen is pretty good practice for tying in dry hackles.
Stacking or spinning deer hair for your dungeons is lots of fun.
but buy yourself a large stacker and gelspun thread first or it will be frustrating.
And practice spinning and trimming the head first on some junk hooks cause your first few will suck.
Have a play with some rabbit strips in dubbing loops and then composite loops for some awesome leeches
have fun
