Next Friday the Speedy DE will be mine! After reading tons of posts about this bag, I am kinda getting the feeling that the Speedy DE is better quality than the Speedy B DE (as far as thickness of canvas, colour etc.). I am really torn as to which bag I am going to choose! If the Speedy DE is better quality I am thinking of just purchasing a shoulder strap for it. Would this work? Any pics of the Speedy DE with an attached strap? Can you awesome TPFer's shed some more light on these bags to help in my decision making?
