New ATI Sirius or LED Powermodule wifi

[Mallsreef]

Hey everyone.
I need Everyones input here, so if you drop past just make a selection from the poll.
BUT PLEASE READ BELOW FIRST
So what is my situation?
Im stuck on lighting choices.
I am going to build my tank soon that measures either:
30inches long x 24inches wide x 18inches high

or 30inches long x 30inches wide x 20inches high

or 36inches long x 24inches wide x 16inches high

Mixed reef but very SPS dominate!

Ati has a Sirius fixture with new clusters for all you that don't know.
It contains:
4x UV 405nm
4x Violet 425nm
4x Royal Blue 450nm
8x Blue 470nm
2x Cyan 500nm
6x White 6500 ° K
Per cluster

I'm thinking of getting the Sirius x4 (4 clusters) or my other choice a 6 bulb led Powermodule Hybrid wifi version.

So what do you reckon fits either 3 of my tank choices best?

The new LED cluster is tempting, but I would definitely go with the LED & T5 combo

I just feel on a 36 inch tank the X4 would be better suited.
I think the hybrid would be fine on the other two tank sizes, any other thoughts?
