For several years I've seen small thingamabbobers (tmb) attached to the top of some large attractor flies, the idea being that they make the flies more bouyant. Help me with this. Since the tmb is on top of the fly, isn't that like saying having a sealed 55 gal. barrel on your lap when you are in your 'toon makes it more bouyant. It ain't addin bouyancy, its addin weight! Or am I wrong? (I have been b4. April 8, 1952 at 3:34 p.m. to b exact.) It just seem like they're doin what us country folk call "pissin on our feet and callin it rain". Help, please.
