Um, I’d get something else, like say the guidebooks and the maps. Unlike the AT, you might actually need them. And, unlike the AT, the maps come with the guidebooks. There are several reasons. First, you’ll want the maps in the Sierra, period. The trail will most likely be under snow and you’ll need to know which little notch you should climb to inorder to get on the other side. Second, there are a lot of good alternate routes, sometimes better than the PCT. You’ll want to take them, the PCT not being the AT. Third, you will frequently find yourself in a maze of trails in SoCal and WA caused by logging or OHVs. It really helps if you have a description of the route and a map. The PCT isn’t blazed like the AT is and you can go for miles without seeing a sign or a blaze.
Yogi will be the first one to tell you: Buy the guides and the data book. This is what I would carry. This is what I did carry in 03.
