Great blog! Can't wait for the actual trip:)I've never ridden with a trailer,so I probably should keep my mouth shut, but I'd go with paniers alone. Less gear to break and worry about and less drag. Pushing the weight will be fun no matter what, but I'd save myself the extra pounds. Also might make parking, locking up, etc. easier without the trailer...But who knows!? All I know for sure is I LOVE Ortleib!!
That bike looks cool! I hope you have a really great trip, too.
