being land based, I would stick with plastics - cheaper to replace, can be rigged "snagproof" (as best possible anyway) and can typically be cast further. Almost anything as far a tail is concerned will work for flathead IMO - they can't help themselves. I do like the Z-Man curly tails though in the 5 inch size. If I had to pick a hardbody it would be hard to go past a Lively lures Micro Mullet. Personally pink or orange is always a goto colour for flat ones but it really doesn't seem to matter much.
