To Plenum or Not?

[smizo]

So I'm looking at starting my baffling and noticed alot of those other homebuilts are using a plenum over the engine for cooling instead of baffling. My only experience with this is working on mooneys (I hate working on mooneys) with the plenum over the engine. All those tiny screws that you always seem to loose a few of. Is there any benefit to an acro airplane to use a plenum? I want the most efficient cooling, so if a plenum does it I will go that route. I haven't seen them used much on acro airplanes so.......???
