Wow, I'm so amazed with all of the thoughtful responses you all gave me! Thank you SO much! The majority seem to want me to keep the Jumbos. I would love to keep them all, which is what I'm considering, too, but no use keeping something you're not totally on love with, right? I'd rather put that money towards something else.
That said, the GST might have to go. It's such a gorgeous bag, but maybe not for me. This is so hard!
