Obviously rigid is the top choice, but as for the purpose of fogs I would choose a dual amber/white pod. Can't remember who makes them but there is a guy on the forum that has them, believe handle is thehops. I personally have cheap amazon cubes 20 a set without wire harness, one of them has developed a leak after 9 months, but can't complain. I got what I paid for an knew that when I bought them.
