Bulb order for T5HO

So for my 4 bulb fixture I've decided to go with 2x ATI Blue+, 1x ATI Coral+, and 1x KZ Fiji Purple.

Question is, what order should they go in? Blues inside, blues on the outside, or staggered like KZ-B+-C+-B+. Or does it even make a difference?

Tank is a 65 rimless (36x20x21). Currently housing zoas, LPS, and softies, but will eventually add SPS.
 
I actually like the ATI Purple better than the KZ.
