When currents are heavy, and you turn sharp, you will more than likely end up with a tangled rigger or 2. Another thing to consider is boat slip in the wind. If you are trolling west of east and the wind is out of the south, your boat is slipping slightly north. If you let the rigger on the one side of the boat down fast, it will fall straight down. The rigger on the other side of the boat is actually angled under the boat (because of the slip) and the other rigger you just dropped with sometimes tangle the other.
