Anyone travel with just 5D2 and 50/1.4?

I keep packing and repacking my bag. Currently I have all 3 lenses, along with a Sony PCM D50 recorder, Canon 270EX flash, Audio Technica mike and Lacie drive.. and a tripod!

Ugh, I could add my Kenko 1.4x extender. But might leave that behind, along with one of the audio plans. Trouble is, I like the mike so AV are together, but I'd rather manage audio file with the Sony.
