Poll Time (Exterminator Turret)

Alright everyone.  I need your help in determining which of the three options I should go with for the turret hatch on my Exterminators. 

Your choices are :

Option A: Center

Option B: Slightly Offset

Option C: Completely Offset

I'll leave the poll up for a week (until next week Friday) and see what everyone else thinks.  The poll is open to the right so vote away!!!
