I would start in the am with live bait. I would normally use scale sardines out in the flats and outer mangrove islands and oyster bars. But because your in the backcountry I would use finger mullet, creek chubs in the morning. In the after noon I might switch over to dead sticking some baits like cut ladyfish, cut mullet, cut pinfish. Late afternoon I would switch back to live baits but they would be shrimp and fiddler crabs. What I really suggest is to have all the baits available and make sure all the anglers on your boat are using different baits during each time and tide phase.
You will quickly find out which bait is working the best at each time and tide phase. It is the beginning on how to pattern fish for future trips.
Another consideration is using artificials if you cannot get your hands on the right bait, you have to get out quick, or you just want to open your options when you're on the water. Our own personal favorite all-time lure for redfish is a Johnson Gold Weedless Spoon, but a lot of other lures work well too.
