Most common is a pre-tied rig. Some prefer a hi-lo (2 hooks). They usually have some type of spinner and skirt. Ther's also a sinker clip. Around here, currents are strong, you have to experiment with weight to see how much will "hold" bottom. Spearing or Sand eels with a strip of squid combined for bait. If the drift is not that fast, rare around here except for slack tides, I prefer using a bucktail with a strip of squid. I've recently been tying a teaser about 10-12" above the bucktail with pretty good results. I kind of "bounce" the bucktail off the bottom. Using live Killies is another good choice up here.
Oh, just don't leave the rig dragging on bottom, you need to lift the rod every couple seconds, almost all hits will come on the "lift", sometimes at the top of the lift, then there's no room to lift anymore and you hit your t-top trying to set the hook

. Actually, last time out I didn't hit the t-top, getting used to that thing now

Sometimes the fluke will hit after the lift when rig is going back down.
You'd probably have a good chance at "flounder" using a "fluke" rig with a finger Mullet down in your neck of the woods.

Or maybe bouncin a bucktail with a dead shrimp on it???
