I have just bought a preloved single flap Jumbo Caviar. I have been told that the double flap has more structure but the leather is more stiff maybe that is has it. The bags from 2008 or 2009 were softer but I wanted it because the hardware was 24k gold plated and the new ones are much much lower. Also the new one with the double flap has more pockets but the extra flap would make things more difficult for me to get into the bag which i know I couldn't handle if in a hurry. I never bought any flap bags because of this but double would be too much.
