You might want to go with the 12". However you will want to use a
good carbide tipped blade with at least 60 teeth. I do stress
carbide tipped, otherwise the flooring will eat up the blade very
quickly.

And even then, you're going to be wearing out a lot of
blades very quickly. The substrate might be cardboard,
but the finish is some sort of very hard ceramic impregnated
resin. I've never seen a blade light up at the contact point
when cutting wood products.

Most of those hard finishes contain aluminum oxide -- the same thing
that's on the high-end sandpaper. I wore down a good blade on that stuff
to the point where it smoked when I cut pine molding.

Two Freud Diablos should get you through a 10 x 20 foot floor.
They won't cut worth a damn afterwards.
