I use double jigs 99% of the time, usually spread out about 2' apart. I always put my heaviest jig on the bottom and the lighter on top unless I by chance am using the same weight on both. I run 4 poles by myself and 6 - 8 with another person in the boat. I experiment with different weights, colors, jig head types etc. until I find a pattern they prefer. I have tried the single jig also, the double seems to produce better for me as well as being easier for me to get the jigs down to the desired depth without putting out as much line. I'm no veteran at this by any means and will be watching this thread as well for any tips.
