In reply to Andy Dorsen:
Genius! Not the first one, though, to build a replica of a route to practise at home. A couple of years ago I saw Heinz Zak talk about his solo ascent of Separate Reality (20 or 25 years after he photographed Wolfgangs Güllich´solo), and he had trained for this for quite a long time on a wooden replica of the roof crack section he had built in his garage before actually getting on the route.
Actually copying short sport routes it is quite sad, though. What I really would like to see is a gym replica of the Walker spur!
