My B-Bag collection has been growing recently and I was wondering which style you use more than another. My first bag was the First but because it was the pony hair and someone told me it was a winter bag I decided to get a city. I find that even though I still like wearing the First, I get more usage out of the City. Yesterday I just purchased the Day and now I am starting to wonder if I will get more usage out of this bag because of all the stuff I like to carry and possibly use it as my work bag. Which style do you find the most use out of?
