I own both
I couldn't decided between them so I bought both. I also did not read where you made a decision, forgive me if I missed it. The thing is I loved both bags but in the end I returned them both. The mother lode jr I probably would have been okay with but in the end I liked the farpoint 40 carrying system. The problem with the farpoint 40 was when I packed everything in it, I lost all the room in the front pocket to pack my iPad and such. It also was pretty bulgy and I worried wouldn't fit in overhead bins.
I ended up buying the osprey sojourn 22, convertible roller. I love it if I want to take a roller but will probably have to check it everywhere I go depending on how it is packed because it is bulgy.
I actually ended up moving over to Tom Bihn bags. I landed on their Aeronaut 30 and western flyer for travel. I love these bags and highly recommend them. They are more expensive if you pay out right and not second hand but it is worth it if you travel a lot. They both also have backpack straps right can be carried with a shoulder strap. I like the halycon versions which are lighter.
