In days of yore, when Jerry Moffatt was a young man, climbing magazines published state-of-the-art articles that told you where and what the hardest routes were. Now we have Big Up Productions. Progression is a no-nonsense, straight-to-the-top run-through of the biggest players on the hardest routes as things stand in 2009. There's a host of stars, including Chris Sharma, Tommy Caldwell, Patxi Usobiaga, Adam Ondra and Team America, jogging up gritstone's hardest routes. As well as sequences from Spain, Yosemite, the Mojave desert and Bishop, California, there's an excellent take on the current competition climbing scene.
