Hi Matthew, Suggest /128's for loopbacks and /124's for point to points, all from the same /64. This way you don't burn space needlessly, don't open yourself to neighbor discovery issues on point to points and can filter inbound Internet packets to that /64 in one fell swoop so that it's harder to hit your routers directly. Just make sure not to filter the outbound packets. Reminder: No matter what size you pick, use nibble boundaries for visual and DNS convenience. So /124, not /126.
