/48s seem flexible enough to me, but perhaps you want to use this technique with /44s or /40s, or something.

Given my unusual network consisting of a dozen different telco's, I actually assign each a /40 at a time, then /44-48 in each of their pops depending on expected growth. I probably could have possibly gone with /36, but then I limit my own allocations to them and I'd like to hope I get more telco's in the future. I do sparse allocation on the /40's to allow smaller routing tables if desired, though. Even for things that don't need nibble boundaries for technical reasons, I usually maintain them for ease of management and scripting.
