I use four rods with 2 hooks per pole, but I will space the hooks out on each pole at a different depths, so no 2 poles are the same, this way I can find out the depth the fishies like that day. Once I figure that out (which isnt all that often) I will move the other rods to that same depth, unless of course your catching at the other depths as well.
I also like to use jis tipped with minnows (hooked thru the lips so they swim/live longer)
I'm sure others will have different techiques:D
