I recently purchased a Speedy 30, and absolutely love it! However, I am also in love with the Vavin GM. I don't need two "big" bags to carry all of my "stuff" around in, and wondered which one you think is the better bag? I like the look of both, but wouldn't mind carrying the Vavin over my shoulder sometimes. And, is the Vavin GM significantly larger than the Vavin PM? I looked at the PM at the Louis Vuitton boutique here in Orlando, and found it surprisingly small. I didn't think to ask to see the GM at the time. What would you suggest? Keep the Speedy, or go for the Vavin GM? Any suggestions would be much appreciated! Thanks so much!!
