The Way of the Light

Merry Christmas ya'll!! I'm looking for your opinions on how I should hang my lights. I did a little moving around in my grow shed and built a new wall to separate my flowering area. The new wall is to make sure there are zero light leaks and possibly do CO2 next time around. I have a 5'x8' floor area with 7' ceiling. I have 2, 1000w HPS/MH with 18" cool-tubes that will be used. What would be the most efficient way to hang the lights? Image A or B?? I'm thinking B.

I think B too....:smokin:

Bump. No one else?? I want to hang the lights today. To me, this seams like a somewhat important decision. Stinky?? :D
