OK, I've got a bit of a problem on how to carry field guides. It's a hassle stopping every 100 feet or so and unpacking them from my daypack to try and identify this/that tracks or flora. I'm looking at small shoulder or ammo bags to hold my gear (guides, magnifying glass, tape measure, notebook, PSK-about the size of a 1 quart zip lock, and water bottle).
I'm partial to the "mildly mitigated bloody great sack" configuration. Something without a hundred pockets (i.e. Maxpedition Versipack).
I'm looking for feedback from anybody who has used them, or can come up with a better idea.

EDIT: This is for front country/park use. I carry a full daypack for backcountry hiking and put the guides in a waist pack. It just seems overkill where I can still hear traffic.
