2 rods per man aint a thang, provided you are proficient at doing so, and they guys you fish with are savvy.
We used to run 4 rods on 4 downriggers and two rods on droppers.
Keep it choked up tight. Heavier weights weights than usual keep the scope of the line to a minimum and help with depth control. Make sure to utilize your wingspan, with longer rods perpendicular to the boat, and the shorter ones off the back.
If you got greenies on your boat, kids, or guys who have never stayed on top of more than one rod, don't even try. Drano can turn into a tangle fest real quick.
