Bigger fish tend to like to be alone. What I do, I don't know that its right but it works for me is, I like to look along the channel on flats with steep drop offs or the main intersections of channels and canals. As far as gear and presentation it just depends for me I'm typically vertically jigging structure, therefore I use my HH Rod and Reels Warpig 13.5 footer, usually with a 1/32 or 1/16 oz. jig head with #8 pound vicious hi-vis line usually with a light weight pegged about 10 inches above it. I will tend to try to stay about 18' back from the fish but you may be able to get closer depending on how spooky they are. I pitch out past the fish and control my fall using the excess line in my free hand. Let the bait fall in a pendulum effect just easing it over the top of the fish, this will generally get a strike. You usually only have 1 shot with these fish I've found so make it count. If you notice your fall of your jig isn't going to be on target quickly pull it out the water and re-flip it. Never stop your bait near the fish keep it natural. I am not the best at trying to explain these things so I hope you could make some sense of it!
