Default PCV, Breathers, etc.

I have read most of the posts here about the various options for how to address PCV, as well as the different types of valve cover/catch cans/oil filler/breather setups on FE engines. Problem is, it takes a lot of time to search and soft through all the info. So I thought I would start a thread where users could post pics and details about their setups. I have found the pics here at the 427 Cobra Homepage to be very helpful but I still don't know that I am clear if any one of these setups are better than another. So, if you would care to, post up your pics and/or details on how your cars are setup, maybe this will make a good thread for those of us trying to decide which route to take.

From what I can tell, there are a few basic ways to design the setup:

A riser (Holman-Moody style) on the back of the intake (with or without a breather or PCV valve on the valve covers) like this:



or no valve cover breathers or PCV but a catch can plumbed from the rear of the manifold down to the oil pan, like this:




...or at least one breather or PCV valve on a valve cover, routed over to either the back of the carb or the 45 degree fitting on the intake below the rear of the carb, like here:




... or no breathers or PCV valves on the valve covers, but a vacuum line plumbed from the rear of the manifold up to the base of the carb, like this:




Thoughts, preferences, experiences?
