If specifically targeting these tiny tasty bottom flatties I would recommend a freshwater carlisle long shanked hook. Easy to remove, normally we weed thru the small ones and keep the larger ones. Flounder, sole or dabs are known to inhale bait, long shanked fast rusting long shanked carlisle hooks allows an easy good for the fish release. Sorry trebles messes up their mouths, faces and makes it impossible to release smaller ones. I stick by the easiest bait idea, small strip (3/4"x 1-2") of herring hooked at pointy end and allowed to "wiggle" as you drift over the sand. If you can afford shrimp for bait???
