. . . which one would it be?

We have the 2010 Thru-Hiker's Companion as well as the 2010 Data Book.

Heard wonderful things about the AT Guide (which as I understand is a comp of the Thru-Hiker's Handbook and the AT Guide?) and am tempted to buy that instead of a Companion for our NOBO thru this year.

Then again there's also the Appalachian Pages to consider . . . .

Decisions, decisions!

What are you bringing and why? "HYOH" doesn't apply here Which book has the most pertinent info for a thru-hike?
