Mono or DE Speedy B 30?

I have the DE canvas and I love it! I don't have to worry about anything when I carry my bag. It's weather-proof and stain-proof, so far. The Mono canvas is cute but I don't have time to baby my bag.
 
De..I'm going to get it today before price increase..the mono I will get crazy if I found water drop to my strap and handle..and if u r those ppl who get sweat easily especially summer time..ur strap will get dirty easily
 
The DE. I bought one two day ago. I was so sure I would get the Mono but once I tried both in stores I fell in love with the sophistication of the DE.

The Mono strap makes it seem more casual, in my opinion. The DE was a lot less 'flashy' and more appropriate for my business casual office.
 
when i was buying my first mono speedy b i didnt have a choice, as de version didn't exist at that time, but i really wanted de for low maintenance and to be able enjoy speedy b in rain, snow - i got de speedy b 35, and i need to say i love them both...

good luck with yours!
