I have and shoot both a summar: http://www.flickr.com/search/?w=50698414@N02&q=summar
and a "red scale" elmar: http://www.flickr.com/search/?w=50698414@N02&q=elmar&m=text
and I think either lens would suit your mission. With the lenses I have, I would take the summar because I think it is adequately sharp when stopped down, but still produces stylish images when shot wide open (where it also has an advantage for being "faster"). I also think the summar handles more easily with the aperture set by a ring, rather than the tab setting on the elmar.
