Ended up with a 2013 50L in green. The 50 is taller than the 44 but when cinched up it is about the same size.
I really dig the green color, and can see using this as a hunting pack.
Couple of cool things about the bag. It will fit a broken down 16" AR so I can go to the range without a rifle case. Also tried it out with my hunting rifle. The side pouches have a pass through that is big enough to fit the forend of the scoped rifle. It is a bit loose and the rifle ends up higher than anticipated, but worked ok.

Tried it out around the block with 30 to 35 lb load and it was good, but I need to figure out how to use the waist strap better.
