T-5's on a 72" tank

I am getting ready to set up a 125G and am wanting to use 6 T-5's for the lighting. The problem is that the tank is 72" long and the longest T-5's are 60". I have made a sketch of some possible light configurations and would like to get some opinions as the a best possible configuration. Any thoughts??
 
I would go with the 3rd option down or the second from the bottom. This gives you even coverage down the middle while you can have Euphelia, blastos, sarcophytons and other less light intense corals on the edges.
 
Number three is basically how I arranged my T5's. You have full intensity of the lighting in the middle, less on the ends. All my sps are in the middle portion with softies at the ends. It's worked great for me.
 
You only really need to consider staggering if you're keeping alot of SPS, and especially down lower. A consistent trait of all flourescent bulbs (even t5) is that as you move away from the center, the lumen output decreases. This may not be by a large % but it does happen. So staggering does help even things out for nice uniform growth on SPS.
