I'm looking at an auction on eBay that is a set; Speedy 35, agenda, wallet, card case. And it all seems to check out. But I'm wondering if the 35 is going to be too big for me? I don't own a Speedy yet, and was thinking about the 30 if I were to get one. Would the 35 be too much bag??? I'd love to hear your thoughts. Thanks!
