At the start, the advice was to configure individual /64 for
loopbacks, however latterly its assign a /64 for loopbacks and configure
/128 instead.
Stick with a /48 for sites/customers.
The best advice is to use nibble boundaries (see:
https://www.ripe.net/manage-ips-and-asns/ipv6/ipv6-subnetting-card)
hence /52 /56 /60
I also recommend watching this (Tom Coffeen from Infoblox at UKNOF35
which covers this exact subject):

Its worth a watch and covers the basics
