Recent observations of other weak-field CVs demonstrate the weakness of present models and make it unclear whether the properties of the brightest systems are typical of the whole class. Our understanding of weak-field CVs ca Co-Is: 1 JULIAN OSBORNE LEICESTER UNIV. UK JULO@STAR.LE.AC.UK +44 116 252 3598 2 SIMON ROSEN LEICESTER UNIV.
