Ok, so I'll throw in on this one, not that I'm a pro at trolling, but do have some expereience at it. I like to troll two jigs just about any time I can. I agree the most improtant part of this is figuring out how deep the fish are and keeping the jigs at their depth and just a little above them If you're below the fish, you will not get bit. I prefer to put the heavier jig on the bottom and a light one above that. I like about a 5' seperation between the jigs. I'll use a 1/32 on top with the heavier jig below. I sometimes will run cork's above a jig if fish are real shallow. I like a southern pro 2" hot grub or slidder which gives more resistence with the curly tail or kick tails and allows you to control depth better, plus added action and vibration. Speed also allows you to work the depth of jigs as well as the amount of line you let out. I can troll 6 rods out the back and up to 8 up front all at the same time with double jigs and not get tangled up too often. A double tied loop knot will keep the jigs from slipping and is a quick easy tie. I use a loop and do not direct tie when trolling. Hope that helps. It's a ton of fun to go through a school and have multiple fish on at the same time.
