We have gone with mostly SLAAC until now, but are about to start 
addressing servers statically.

The VM or "your MAC is fixed, or can be changed" argument unfortunately 
doesn't hold for OSes like Windows 2008R2, which use a random number in 
place of their MAC address for the SLAAC suffix, so if the server is 
re-built, it re-addresses. You can certainly disable that, but the 
effort required is actually greater than that required to configure a 
"neat & tidy" static IPv6 address.
