I'm so bummed they didn't think of this sooner. This new layout could have solved all my problems.I prefer the Modular Marine ghost overflow because of its solid and sturdy acrylic construction. I had the Synergy Shadow but ended up selling it. The injection molded construction just felt a bit flimsy to me. I thought there seemed to be a good bit of flex with the exterior box.
Apparently, Brian at Modular Marine has been listening as there seems to be a new hole layout in the exterior boxes to allow for more room for plumbing.
