Among the amalgam of guidebooks and maps for the Pacific Crest Trail, which guidebooks and/or maps are be the best contenders to bring on the trail?
Guthook 2010 review is no longer available. It recommended Halfmile maps, which is still available in March, 2018, combined with PocketPCT, which is not available. However, postholer maps are not considered in his review.
Guthook provided an excellent answer to this question. Since it's no longer available, there's no way to know if it still holds true.
