For the spring mostly classic nymphs and some nymphs which doesn't look at something but saved sometimes my fishing day.
For example this small tiny nymph (hook #16) with a glass bead on it and some peacock hearl and madeira yarn
Great tie! I like it.

I can't say about fly fishing but there's a lot of feed lots in Kansas.
