Herbie overflow w/ megaflow

[Tobykourtney]

I have a 125 gallon aga megaflow and was debating on running a herbie drain with one side and having 2 returns coming out of the other side. I was going to do both sides as herbie's but I feel like it'll be a huge pain to adjust using 2 gate valves on the same system. Any input would be greatly appreciated.
