The New Old Rig by Scott Ross

When spending time on the water your mind can wonder. Spend enough time, and it just might wonder in the right direction. Every once in a while someone comes up with a design or breakthrough that makes you go "why didn't I think of that?"
I use a rig that consists of the basics. It's a pole, line, and a HOOK. That's all!!! No sliders, no bobbers, no sinkers, no nothing.

Why does it work so well? Well, to begin, It's easy to setup. All you gotta do is tie on a hook. What makes it so special? Lots of things. When you hook on a chunk of cut bait, The bait can fall at it's own natural speed as if a bird dropped it. Every little bounce of the water pressure makes the bait move as natural as any other chunk of dead fish in the water. If your throwing live bait, without a sinker weighing it down it can stay alive and healthy a lot longer. And a live bait is gonna swim to wherever a live bait is gonna hide. A large fish knows where to look for food.  However if you are in tight areas that can be a downfall.

This rig does work well in slower current as well. The lighter weight allows the bait to follow the natural current seam and fall wherever a chunk of food would land on any given day. The fish in these areas know where this is at and will sit there and wait.
Any body that fishes a lot or even a little knows that snags happen. If you never get a snag, It probably means your not fishing the right habitat. The slower movements of this rig prevents as many snag hookups.  But if you do get stuck, and break the line. Your cost is at it's bare minimum.
Wind can be the worst enemy for this setup. Windy days can blow your line and pull your bait around where you don't want it. If your trying to drift, the wind can blow your boat fast enough to pull your bait off the bottom and cause it to spin and damage your line.
Fast current can also prevent the effectiveness of the bait. It can prevent it from falling and settling in a current seem.
To make this rig more efficient you need to keep the rest of your gear at peak performance. If you can't cast it, Your gonna have trouble fishing it. Also a decent line, preferably braid, that can sink with the bait can help keep it down better and let if fall naturally. Not to mention how much better the braid will allow you to cast.
Give it a shot. I think you'll be pleasantly surprised.
