I would think that a main factor would be how much labor are you planning to hire? I'd bet the guy in Wisconsin has many young, strong backs to have double deeps on everything (which would be awesome!).
But if you are planning on doing a lot of the work yourself, having a one deep, one western configuration seems to solve some of the problems and reduces the weight of that top box. Hopfully, you're not actually having to life the bottom one unless you're cleaning bottom boards, and even then they can be tipped.
I know your young and all, but once you start tweeking those back muscles, it's really hard to get them right again.
