Sometimes very visible and loud bites race. Like a lot of fish i guess depending on what there feeding on and how aggressively as to how they hit the baits. Any "Rig" will do, but like chris i just stick with my pulley rigs. Hook size 3/0 to 6/0 ideally but you will catch on smaller and larger hooks all dependent on how mean or generous you are with your bait sizes. I use 4/0 gamy circles for a nice glob of craytail bait, or half a dismembered shelled paddle crab. The lemons are pretty thick round here at the moment, and will continue to be right thru til winter time.
