Not necessarily Byron, but I do put a bright green z-lon butt on a few just to have in my box. I fish few elk hair caddis, most are just old simple x-caddis, shuck, body and deerhair. If I fish a palmered body fly it is a Henryville in different colors. My other caddis patterns are the LaFontaine series of pupa and emergers. Most of the waters I fish here in Ct and catskills are much slower with long flat pools. Sparse patterns seem to be prefered.
