I'm moving to another city. All my belongings fit in a backpack I bought. I also have the option of putting all my belongings in a rolling suitcase. I have a sleeping bag. There is more room in the suitcase for things but a pro for the backpack is that I won't have to deal with it as much as it'll be on my back. Cons include weight. It does have a back support/waist band though. Which would you take?
