sounds like my dream set up with the 10 600s.......i'd flip flop 5 and 5..no cool tubes just batwings and a big exaust fan in each room.10" at least with a 6" intake.I do agree with the person that recommended lr 1000s though......go look at the sealed room 3lbs a light thread by tranoble.absolutely amazing.....anyway good luck with your endevor hope all goes well.
