LOl! I know what you mean. I was going to purchase the speedy b back in the spring but instead i went for the regular in size 35. I love it!!! If i ever got another mon mono bag i would choose the speedy b this time in a 30. Since you already have a speedy in the classic version, the b may be a nice change. But I know some people just adore the classics more. I do myself. What colors are you thinking of getting?
i'm thinking about the vertical stripes with bordeaux in the middle and black on the edges and using dots with my initials

i'm really fond of the classic version, especially for something that would be special like mon mono! i just cannot make up my mind on the size!
there are way too many options!
