Pump choice for new build....

[minus9]

I'm in the process of building a 90g shallow tank, 36x36x16 and want to keep it "clean" looking. It will be rimless with a floating canopy, shadow ghost overflow on the center back. I have a pair of 6040's that I was going to put on the back wall along with my two returns. I'm thinking of adding two 6095's to the sides or front corners pointing back, but thought about adding the Stream 3 on the back wall to eliminate the front pumps? The rock will be minimal, roughly 40 to 50lbs, half of which is tabling rock. The rock will be "open" in the center portion of the tank and not near the glass. It will be a sps dominated tank, so flow is very important. Also, I'll have some rock glued to the back wall for some tabling sps.
There will be sand, probably 3/4" to 1" deep.
Any thoughts on pump choices?
Thanks!
