Hi everyone! I'm been reading the forum for a week or so and I just wanted to introduce myself to you. I've recently discovered this forum on accident and you girls AND guys are awesome and know your bags very well. I'm 23yr olds and about to graduate so I'm looking for a awesome new bag to buy so it can start work with me. I'm very much leaning toward the Daimer speedy but I have a small problem choosing the size. How much difference is the 25 to the 30(besides the price)? Pics would help a lot. Point in mind, I'm really really short, like 4'll short but I like big bags..... thanks for reading.
