I think this will > be a more stable situation than scaling down from /6s to /7s (as Gert > suggested). However you label it (/8s that can grow into a /6, or /6s that can be shrunk into /7s, if needed) doesn't make a real difference. The important thing about the "/6 approach" is that the initial /12s (growing to /8s) are allocated with so much room in between that you *can* grow to a /7 or /6, if necessary, and don't have to start a second (or even more) block per RIR.
