Drains

[pirate]

Well I just got a 150g tank withstand, and its set up with a durso drain. A overflow box in one corner and the return in the other. I'm just stettiing up my sump ( gonna be a 50-45 g) inside of the stand. Currently it plumbed for 1 inch I think. (havent messured it). But because I'm setting up my sump I was thinking about going to a herbie drain. Just changing the return into a higher drain. I like the idea of a emergency drain in case of a plugged drain. But will a 1 inch pipe get plugged? I know with 2 drains in the overlow box it would be easier to set up a heribe drain but can it be one at seperate corners? It wold just be a lot of mesuring to make sure it was at the right height.
So is it worth setting this tank up as a herbie? or staying with a durso drain a better idea.
I don't want to drill another hole in the tank. If I do a herbie I'll send the return up the back side and over the edge into the tank.
What do you all think?
And thanks for the advice
