Since I first encountered tpf. I've read so many threads asking opinions about what size of Speedy to purchase....anyway my best friend (who is a guy) told me about something he had heard on a radio program regarding bag size. It's not only your height you have to consider, it's your build. If you are even just a little overweight, a small bag will make you look bigger, so I guess carrying a larger bag will make you look smaller. He did not tell me where he heard this, he just thought I would be interested. So I'm sharing, because you know, someone is going to ask....it might help someone.
