Downside: you're burning extra memory, to the tune of 6 bytes per page.
Downside: there's some additional overhead in maintaining a larger FSM
Upside: you have room to grow, as well as to accommodate occasional
bursts of update activity
Both downsides are pretty minor, I'd say just stick with what you've
got.
