Would it be overkill to use the center pole and end poles on the WD12 at the same time? Would it be feasible?

I got the mod for both and I have both poles. I haven't quite figured out the advantages or disadvantages for using center and/or end poles. Now I'm trying to figure out which of the two I'd like better... then it hit me... maybe use both? I haven't tried using both at the same time, but I wanted to get opinions first.
