When I say "see whats going on below the surface" you need to find out what the fish are feeding on and the first thing you will notice is the redfish, trout, and black drum switch from eating 75% fin fish IE: mullet, pinfish, pigfish and mud minnows to eating almost 100% crabs, baby horseshoe crabs, shrimp, snails and even sea horses. The reason behind this is the shrimp/crabs and so much slower moving than the mullet/pinfish making them easy meal
So with that in mind everything you do on the flats needs to slow down as well. I like to use soft plastic lures or flies this time of year like the D.O.A shrimp and the Exude crab and the Gulp shrimp and for a good go to fly try a closer. When using any of these baits make sure to work them the same way the real thing would move in the water so don't jerk a crab like a jerk bait or twitch a shrimp like a twitch bait. I also like to use some sent products like Bioedge in the shrimp or the crab sent, in fact the crab sent on the Exude crab is my favorite thing to use this time of year because you can rig it weedless and use it to find the fish that have there heads in the grass looking for crabs and such to eat. Look for the edge of floating grass or the sand holes on the flats, both are good areas to find fish waiting for a meal to swim or crawl by. This should help you find and land more fish this winter. Oh yeah don't forget to use sun screen or a buff to keep the sun off you.
