Are you looking for eating fish or a fight?
Bay fishing, I suck at. But if you are looking for a bull red(over 35") I can help. I use about a four foot leader of 80# mono with a 12/0 circle hook baited with 4" chunk of mullet. Treeline on the bottom with your reel out of gear. When your line starts running reel in quickly to set the hook. Don't snap it like you would with bass.
These were all caught in the Gulf in about 16' of water.
As for fishing the jetties, here in Texas that'd be a better spot for kings and smacks than reds. If you get into kings your gonna want a little more reel than a bass rig.
