Is it possible to record (with Logic

Which connection do you suggest? i once read that FW is more stable than USB2.
If i take the FW version of the mkII can i daisy chain it to the 8pre??
How about the control software. if i use both devices at the same time, do i need two control pannels (Cue mix DSP)???
Can Logic handle recording from both at the same tme??
Thanks a lot for help.
