Ignore the top 50 routes the ones I did were lousy. Some of the grading in the book is under graded, to what you actually find on the rock [a few 6A's are 6B+]. If your using the toppo to guide you to the lower off you might be suprised (the one route that I actually used the topo to guide a friend didn't have the lower off where the the guide book said it was, and the lower off was a few metres below to the left). But lets face it your going to El Chorro to knock off some 8a,8b and a few 8c+s you'll be fine! its still an ok guide book.
