Anxiety doesn't necessarily cause concentration problems as its own symptom. In fact, it could be argued that anxiety actually improves concentration. Anxiety is the activation of your fight or flight system, which is meant to keep you safe from harm by ensuring you're running away or fighting without distraction.
The first set up is a standard 20-25 pound test rig (depending on the size of the tuna) with a size 1 to 2/0 hook depending on bait size and the size of the tuna. Fluorocarbon leader can be super effective if the fish are touchy (biting infrequently). This set up will be the primary bait fishing set up.
We don't leave without spreader bars in all sizes and colors, Tuna Trains in all colors, teaser birds, multi-size ballyhoo with teaser rigs as well as lures. If we are trolling for giant tuna, we will start with 13 squid spreader bars and go to smaller squid rigs if there is no action. Match the hatch.
