Lighting options narrowed down. 3 xr15's, 2 xr30's or 2x 30's and 1x 15????

I have been researching lights for my new tank 48x30x25.
I look at AI Hydra HD's, Radion Gen 5 Pro's, Kessil and even looked at the Sky. All my research was par, spread and how high they can be mounted

I decided to go with Radion Pro Gen 5's

I need opinions of what directions to go.

They will be mounted 10 to 12" from the surface
The tank is 30" wide with a center overflow and NO center brace. It also has a black background

My options are

3x XR15 Pro's
2x XR30 Pro's
2X XR30 Pro's mounted front to back and 1 XR15 Pro in the middle My LFS suggested this "perfect world money no option" suggestion

Granted 2 30's will cover
3 XR15's will even out the coverage
but 2x 30's with a Xr15 in the center would cover me for life

Asking for opinions
