I am about to purchase a 4 ohm C8 Piranha and matching D1000. I intend to fly with this rig so space is important. The C8 is the biggest cabinet I can fit into an airliner. Would you please comment on this configuration vs D1000 with two 8 ohm C8s? I've read that dual cabinets will "move more air" and therefore sound louder. Also less stress on the rig. I always prefer piranha but with two cabinets maybe I don't care. My opinion is: dual cabs would be a little better, but one 4 ohm cab will work fine and much less hassle for flying.
