Interior cage

I think I have decided to hold off on the exo 'till I get an inside cage built. I have just one ?. Is it stronger to go from left _ pillar to pillar right _ pillar or start @ A pillar & go back towards the rear. If that is confusing, what I'm asking is from left to right or from front to back stronger? TIA

equally built, with equal tie ins to the unirails, it wont matter

Thank you.
