For v4, I have my forwards and reverses cut up into multiple files that cover a /24 each.  This makes for tidy files, and lets me get to what I need to change quickly.  For v6 I can't see doing that for /64s, obviously, or even /48s, unless I just set the files up as I need them.  Reverse gets even more tricky.  I'd prefer to run with origin statements and PTRs of a reasonable string length, but again, do I do this at the /48 level?  An origin of /48 still leaves a long string to work with.

Tim,

Some old hands at naming and addressing management would suggest organizing A/AAAA zones based on naming authority and natural breaks in the DNS tree.  Then create PTR zones with whatever automated process fits your business.  Worrying about some poor human and string lengths is counter-productive.  

As Norbert Weiner would, consider the "Human Use of Human Beings". In other words, create zones to follow the business requirements for management of naming, including delegation of authority as required, and let automation satisfy any PTR requirements.
