Over in Mobile Bay, I have had better luck on Blacktips anchored and chumming with pogies. Two rods with balloons, and 2 rods, staggered distance, on the bottom. We have caught a number of blacktips, plus big Crevalles and every year we have a tarpon sighting.
I am not sure if the fishery is much different over your way but just east of you I will see them and spinners crashing bait in the mornings. I do not typically specifically fish for them but once they get consistent, I will go back in the areas and locate them and then pitch baits back in there area.
We've caught some big bull sharks doing the same. Balloon and a loooong leader so you don't get tail whipped. Baits either Spanish Mack's. Pogies or white trout or skip Jack. Really just what ever we can get.
I caught one every cast today at cat island in Mississippi. They like murky water and will nail a live croakers too, but so will a big trout or redfish. Very very good eating fish just be careful cleaning them and don’t hit that urethra sack. ( we cut them all lose as we were trout fishing?
