I've tried to wear it on just my shoulder and it totally knocks me off balance. So I try it cross-body and it smashes/separates muh bewbies while still yanking on my neck. I bought a new backpack awhile back but it was just too big (which I thought I wanted). And the spot for my laptop unzipped all the way down, which I originally thought was going to be super helpful until I didn't lock the zipper and it opened on its own while rushing through the airport, spilling out my laptop, charger, ipad and whatever else was in there. Twice. But I definitely prefer the even weight distribution, so i guess I'm on a new mission to find the right backpack
