How do you fish plastics under a popping cork? Just jerk it every couple of minutes or something?
When fishing running bait in the current, I just use the cork to keep the bait in the feeding zone as long as possible. If not getting hit, then give it a pop. If no signes of bait or fish feeding, then I usually loose the cork and just cast baits. I too prefer just a circle hook under a cork, although I will use jiggs in rougher water.
Also I will use a jig under a cork when fishing for flounder in the marsh. Rig the bait to where it is just off the bottom. I usually put a pinch of shrimp or spray on attractant on the bait. I dont really pop it as mush as I drag it slowly towards me and let it fall back. You can tear up some flounder doing this.
