ILBE is essentially an Arcteryx Bora on a smallish frame... for a better fit for many (most?) users, the Bora 80 and 95 are going to work better and be more comfortable.
The photos above pretty well illustrate the point... that pack is too small for HatchieDog... a taller frame would give the load-lifters the ability to work and add a LOT more comfort.
Just a head's up...
