I have been admiring the YSL ROADY FLAP BAG in black since it came out this fall. Are there any owners of this bag out there that can give me some feedback as to how easy it is use? Does it keep its shape? Overly heavy? Is the flap annoying to lift to get into the bag? I LOVE THE LOOK OF IT, and as some of you may know I am a big BV fan, but I am seeking a bag with more structure.. To me it has the look of an HERMES Kelly..Any thoughts or suggestions? TIA
