Definitely speedy b. I've bought LV bags for years and never bought a speedy because I like bags I can sling over my shoulder. But once the speedy b came out I couldn't resist it. It is probably my favorite of all the LV bags I've owned, primarily because of its versatility. I've actually found there are times I like to hand carry a bag but I have the strap when I need it. Good luck with your decision.
