I used a Speed Demon for work on a daily basis (I'm the staff photog at a newspaper) and it's an unbeatable tool.
Granted my camera is always around my neck, the bag is perfect for smaller lenses and other stuff.
ThinkTank is great, because you can build a bag only to the size you need by adding on the side pouches and bags.
Great products designed by real, full-time professional shooters.
