I'll be taking two upcoming SQ flights: PVG-SIN and SIN-BKK in C. I am a professional photographer and typically carry on, in a canvas camera bag stored in my rollerboad, two camera bodies and four lenses. My bag will certainly weigh over 7kg, although I know from past experience that many airlines ignore their 7kg rule for those who are flying in C or F and/or are carrying expensive photography gear. I'm also *G, if that makes any difference.

Thanks in advance.
