Merlin MMe - Bi-Wire or Single Wire

I am a little unclear as to what Merlin recommends...it seems that they want a single run of wire with the jumpers utilized...anyone confirm this?

The reason for the question is that I have them bi-wired and sounding great, and it is a pain in the neck to undo the amp side of this bi-wire arrangement...if I am totally wrong then I will keep things as is...

Thanks
