Double up on 3 of them.
I put this on the structure forum but no one seamed to have a opinion, so I thought I'd put it on here where Everyone has a opinion:
There is a set of covered docks that has 6 12" poles around it. I've made 6 PVC structures and put 2 of them on 2 different poles. Would you put 1 each on the others or double up on 3 of them
A person should learn something new every day!
Double up on 3 of them.
Be safe and good luck fishing
I'm going to make the assumption that poles run shallow to deep. I'd put one at each pole. That way if you have fish moving in and out they have something to hold on. Remember it does not take much depth difference for fish to move or hold. The poles the selfs are a good spot but cover around the pole makes it even better.
