sounds to me like a lab scenario. and while it may not be a good idea in a
production network, it should still work. gonna try labbing it up as well.
what code versions you running, Adam?

I am not sure what is happening for you, but as a general rule of thumb I
don't run per-packet load sharing on circuits that are not 'the same'.
The need for packet re-ordering goes way up when you are running
per-packet on two types of circuit. Are the circuits provisioned for the
same speed at least?
