Not your side of the Country but always looked forward to fishing for Shad on the Russian River in Nor-Cal. Flies were very similar to the one RT's got on display above. 'Best one' for me was just a bit of red Amnesia shooting line and chain bead eyes. Worked a treat; close second was same fly made with Chartreuse Amnesia.
The one key factor was the use of a clear slow sink 'slime line.' No idea why that was such big deal (vs just a sink tip of some sort), but it was a key factor in multi-hook up days.
