I don't have one because I tried the 25 and the 30 and wasn't sure I liked either one, so I sent them back. The 30 sagged a lot more than the 25, though, with my stuff in it. My daughter has the D&B barrel bag and that doesn't really sag at all, whereas either Speedy is going to sag a lot more than that, moreso with the 30.
Don't know if you're set on a Speedy, but after the Speedy didn't work out for me, I bought a Batignolles Horizontal, and I love it! I'm more of a shoulder bag person anyway, so it's worked out well for me. It's not a lot more than the Speedy also, so it's a great started bag if you don't want to spend a ton on it. Let me tell you, I load that baby up and there's no sag!
