+1 on that, and I think it's very valid in this discussion about them. I don't have a CG-500 to see how it fits with the cat 5 cables etc, but I feel your pain with the stiffness of the cables in the cold, they were a pain to corral when I had to get it open, and those little side clips were really difficult to pop out in the cold without a lot of fiddling.
I will likely use 4 core connectors as those I have on hand, and they simplify power injection should I need it sometime.
