I think the speedy held by hand very elegant and the epitome of classy (search Audrey Hepburn and speedy to see what I mean). The Westie, imho, is not as classic and may be dated in a few years.
I go for Speedy B also!!! I have the DE Speedy B 35 and I just LOVE it!!!!! And the more and more I use it...I ask myself...why didn't I get it sooner (well, when they came out with the DE version). It is very roomy too.I've had both. The westminster GM is small for a GM size bag. With the speedy b you are getting two bags in one. Speedy B gets my vote!
