crystal1313 - I bought myself the BFF streamline tote and it IS lighter since the belts are straight across. The BFF convertible clutch is 15.6 oz. empty, and the BFF streamline is 1 lb. 6 oz. empty. I just weighed mine.

The only problem with the streamline is that I feel, for the size of the bag, the strap is too narrow! It's exactly the same strap as on the convertible clutch, so if you load your streamline down, the strap will definitely cut into your shoulder. You can order a thicker strap from Harveys but it costs $20. I got one and it made a huge difference. But if you're not a heavy packer then the thinner strap will probably be fine.
