Which is more versatile.... the mono Speedy 25 or the Manhattan PM. ? I love them both but don't know which one to go for. I already have the mono Speedy 35 for everyday and use it a lot. But the Speedy 25 is a totally different size and I can see using it for different purposes. Also, there is a big price difference. Also, I am not a Damier lover and really do prefer the mono canvas. So... what do you guys think?
