Familiarity: I've put it through the wringer
I own five of these bags (3 medium, 2 small). One I've had for five years, the others for about six months. I would highly recommend the medium size as the most versatile and useful. I prefer the older one, but my two new medium ones have done well. All three mediums traveled as cargo from DC to India with no issues. My only complaint is the smalls, which I bought to use as carry ons for my two boys (2 yrs and 2 months), the slip through pocket is too small so they will not fit over the handle of a rolling bag. You can still put them on top with the handle throughout the carry handles of the duffel, but this can knock the rolling bag off balance and causing everything to fall over. Very annoying. This is not an issue with the medium, if fits fine. I say go medium.
