After using my speedy b for a few weeks, I decided to use my regular speedy. I haven't used it since the fall and decided it needed some love. Honesty, I prefer my speedy b due to the strap. It was a little annoying having to carry the regular speedy in the crook of my arm and since I had some heavy things inside, it left marks on my inner arm. Although I do love the look of the regular speedy including the sag, the strap is SO much better and more comfortable. I don't think i will ever buy a regular speedy again.
