Kind of and old topic but just so people know you can use an A-rig with one hook and four dummy baits on it.
I was fishing on Table rock last month with a guide and we threw the A-rig and from what he said is the bait that trails behind the farthest gets hit the majority of the time, also the youtube vids on these seem to say the same thing. I'm going to try the rig in a couple of variations. One being all the same color baits with one trailing behind and one using spinners and grubs as the dummy baits.
The only bad thing is not being able to double up in MN.
