Have L3+'s now, D3's coming in, can only keep one.. What should I do??

OK, Here's the poop!!
Right now I have 4 L3+'s happily mining away.  I have 4 D3's that should arrive in the next couple weeks.  Problem is, I only have 1 circuit on 220V and can only keep 4 miners.

Should I keep the L3+'s and dump the D3's?
Keep the d3's and dump the L3+'s?
Keep 2 of each?

Running another 220V line is not an option, plus the noise and heat from 8 miners is also not an option.  So what would you do?

No question keep the L3+.
They need less power and the income is higher.
