Two Nikon DX bodies lens choices?

I have the D5000 and the D7000. Sometimes I will go somewhere and bring both of them. I'm wondering what lens i should mount on them. The D7000 is better camera so I think I should put the lens with better use on it to get the best quality image. I have a 50mm 1.8G, and 35mm 1.8G. So I have to decide which one to mount on which. This is a hard decision, you'll probably say just switch them around. I need to know what you would put though.

Added (1). Yes I have a 18-55mm and I rarely use it.

I choose the lens most appropriate to the situation and mount that on my main DSLR and then put the other lens on the second DSLR.

There really isn't that much different b/t 35 and 50. The 50 is better for shooting portraits.

Hopefully you have an 18-55 kit lens, right? If so, put it on the 5000.

Do you find yourself needing the 35 or 50 more? Put whichever lens is more useful to you on the 7000.
