A 2 strap bag will definitely be more comfortable if you load a lot of stuff. But that bag would be fine....if you don't carry a lot of stuff, it's pretty tiny. I think the Citizen would be a better bet, you can always carry less but if your bags too small for what you need to bring, you can't make it bigger. This persons 5'7 and they're not swimming in that size. http://imgur.com/a/cdDMj
