It will have slightly more pack with the 4 hole, but not because of the area for the oil to travel through, but because you will run lighter oil with 4 holes than 6 to keep the same static damping... and lighter oil tends to pack more easily than thinker oil.
I think what you are looking for, is something like a 6 hole 1.1, with very light oil... maybe 20 or 25 (not sure.. just tossing it out of my head, i would subtract between 2.5 and 5 from what you are running now, with the 6 hole 1.2). That will give you the same static damping as the 6 hole 1.2, but more pack.
