Hi - I am trying to pick just one bag for an upcoming trip (mostly city, mostly walking) - which of these do you think is best option? Jypsiere 28 Halzan 31 Bolide 30 1923 Kelly 35 Other? I have used a J several times before while traveling. I always think it's going to be great and I end up finding that I fiddle with getting in and out more than when just running errands at home. I think I would want to keep the Halzan handles buckled, and that makes it more of a chore getting in/out (although it has the back pockets available for phone, etc.). I have never traveled with the Bolide and just twice with a K, which I found to be a bit big for the purpose. Also I tend to carry an additional shoulder/handheld tote for purchases. Any opinions/insights are much appreciated!
