I just got a damier speedy 30 and I love it!! Anyhow, the sides of mine sorta 'sag' eventhough I have a magazine or something sturdy on the bottom. The only way to explain what I mean is by this picture which I found on eBay. http://i10.ebayimg.com/06/i/000/bc/10/3c6e_12.JPG Does anyone know how I stop my speedy from doing that?? TIA.
