Not familiar with that rig
but if you hang around you're sure to see one come out of the water :) Also, I'm not sure but the fish from Apalachicola Bay should have no obstacle when they swim upstream to this point. Figure out when this event occurs and mark it on your calendar. The Striped Bass will take other lures too - these folks are probably trying to reach the wash-out below the spillway like a catfisher would, with some sort of bait.
Catch the run and you can get 'em on topwater baits like the Super Spook. This is my favorite way to encounter the Striper. To see him come up and take it and then make off like a freight train. Do this once and you'll be hooked too...
