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 Cheers
