i use blue and white flatwings, eels, deceivers and clousers all the time for stripers - but only on sunny days.
i read a few years back that the fish see it as a green in their spectrum on bright days.
since then - chartreuse for dull days, blue for sunny days and root beer or olive for the flats.
i remember one guy looking me a little funny down in Chatham on the Cape, til i asked him what colour are snapper blues....lol
that fly would work well for a baby squid around the docks when they're in.
your main problem will be getting it down - did you wrap lead on the shank ?
if not fish it on a fast sinking line over weed beds and strip and pause - it'll fall on the strip and rise on the pause. which in my experience is absolutely irresistable to bass and stripers.
