Regarding Guyzo's post above...
The equation is simple: the more specific beta one includes in a guidebook, the more mistakes there will be. One persons "orange alien here" is anothers pair of stoppers 10 inches below leaving the cam placement open for the fingers...
I much prefer doing things my own way over relying on a detailed topo full of beta.
I also think that a well organized and well thought out guidebook can really enhance one's experience climbing. To know who did what and when... To be able to know what and where the established climbs are... These things don't take away from one's adventure but rather facilitate it. We do, as climbers, walk in the footsteps - shake hands, as Guy put it - with those who were there ahead of us.
Earlier this summer I saw a couple guys do two badass Needles routes in the same day: Romantic Warrior and Don Juan Wall. They did not have "supertopo" type beta so they were on their own in that sense, but they had info as to approaches and where the routes are, how many pitches, grades, etc.
I think they had a pretty good adventure...
