Fibre Management Best Practices?

Hi all,

I am looking a 'best practices' document on fibre management. Short
of that, something that outlines/highlights the benefits of going with
a fully patched rather than direct spliced optical network design.
Ie a document that shows:
device <-> patch cable <-> patch panel <-> splice tray <-> splice tray
<-> patch panel <-> patch cable <-> device

Is better than

device <-> pig tail <-> splice tray <-> splice tray <-> pig tail <-> device

For the sake of troubleshooting, flexability, management.

It's a turf war, I need some ammo. More specific details available off list
