Your overflow design: what would you change, what do you like?

[Hal]

I'm in the planning stage for a 260gal tank: 72x28x30H. I plan to have a two internal overflows spaced in from the corners, with 3 holes in each to run a Herbie. Tank will be in the corner with only two sides visible. I expect access to the overflows will be difficult, but hopefully not needed often.

What advice do you have on overflows? If you did it over again, what would you change about yours?

Thanks, I've seen the beananimal, but I prefer the Herbie. I don't see the need for two backup drains. That just takes up extra space forcing the overflow to be bigger. I was thinking about things like moving the overflows into the corner, using a single larger overflow vs two smaller ones, teeth size, adjustable teeth height, opaque vs clear, etc.
