These are my favorite flies for stream dollies... The top is just a wet hackle with a pink abdomen (primrose thread) a couple turns of peacock for the thorax and a speckled buff-colored wet hackle... This happens to be from a bobwhite. I use a lot of partridge and green, p and orange, p and yellow on short shank hooks from 8-14.

The next down is essentially a Thunder Creek with beadchain eyes and the body is Sulky brand blue prismatic thread which I use to tie the whole fly. It is a little bulky...

The third is my version of a scud, with feelers. I believe the fish take these thinking they are sea lice. For a while after the salmon arrive the dollies eat just sea lice... Typical flashback, I add burnt mono eyes and a couple strands of silver pheasant for feelers.
