Everytime I use my Damier Ebene Speedy 30, then use my mono Speedy 30 I feel that the Damier is a little bigger. I'm sure this isn't the case, but I was wondering if any of you feel this way, or is it just me? (probably just me) Could it be that the canvas is different in some way in each bag giving the illusion of size difference? I don't think it's that the Damier feels that it holds more, it just seems to look larger to me.
