Personally I would use the midbreak for the break and set it to 70% (71 to be a bit more exact). In a sense, the way they are now in the sim, the aft turrets would be at the same height as the two forward turrets. Other than that, nice ship and nice pic.

Considering that you have 6 TTs (most likely 2x3), would it not be better to have either 6, 9 or 12 reloads?
