I have been told that the best way to rig is with the wind, as the fish sit in the water facing the wind. Wanting to experiment with trying to slow the boat down and going with the wind. I have heard that some drag chain, I want to try this but have no idea where to start with size wise, I know it has many variables, but just a starting point is what I am looking for, 19' deep V boat. 5/16, 3/8 chain? How long of a chain do you drag? I just have no idea how much drag a chain would produce, I assume that also the bottom being mud or rock would make a big difference also. Thanks in advance for any thoughts on this!!!! Mark
