Ricardo, I suggest you drop by Monochrom - www.monochrom.com - when you get to Berlin. They have both an exhibition, and a wonderful selection of film. My first choise for the kind of look you want woud be MACO - either UP400+ or CUBE400c. The CUBE film is one of those traffic surveillance films with extended red sensitivity. Combine it with a red filter for daylight use, and you're right up against the border of IR photography.
