Overflow placement on 300g (96x30x25)?

[Black Mammoth]

As some of you know, I'm planning on putting in a 300g tank. I'm trying to figure out what kind of overflow to use. I wanted an external overflow, but Glass Cages doesn't offer that option. So I'm trying to figure out which ones to get. I'm not a big fan of the two in the middle of the tank, but they do have a couple advantages. I'm also looking at the corner overflows. But I may not want to do those because I may have the tank viewable from two sides (front and one side).

What would you guys recommend? Do you think that the corner ones would be sufficient in top skimming?

You can have it on one of the sides, making it possible to be 3 side viewable. Or you can just do it in the center, and have a calfo style one. Center has an advantage if you want to use a wavebox, it'll be the axxis of the wave, so water is always draining below. And as far as top skimming, I think either would be fine. I have my return blowing across my surface, to agitate it.
