Randy,
I'm answering on my phone so I can search the difference between the Falcon and Pigmy. However, I'd steer clear of a pack that is too big because for GHB usage. Drawing little attention to yourself could mean the difference between life and death. Having said that, I would consider taking your BOB when you travel over 45 miles. The reason behind this is, even trained hikers rarely exceed 15 miles of cross country travel in a day thus 45 miles is already 3 days of brush busting. Resultantly, the GHB will be too small to house enough consumables.
