I've been contemplating getting an MC Speedy. Problem is that I own only 25s (in both Damier and Mono) and it seems to be enough space for me. I do love MC a lot, but I wonder if my wanting an MC Speedy is just a wanting for another MC piece. Do any of you own different sized speedies? If so does the larger one make you feel bogged down by the weight or does the empty space bother you at all?
