Gyre size question

[Brew12]

I have a new tank on order. 60"x30"x24".

Which of the Gyres would be better for a tank this size. The 230 or the 250?

I would do 250 it’s not much bigger and has almost double the flow

I've got twin '50s at either end of my 220 tall, and there's _plenty_ of flow - with another 30 or 40% to go in the "forward" mode parts of their cycle. I like having bi-directional flow, and I like having some reserve, just in case I need it down the line.
