Litz established Peruvian Necktie and Ace of Spades in Utah's off-the-beaten-path Pop Tire Cave. Woods made the second ascent of the latter, which he thinks is 5.15a, and thinks the former could be even harder.
Here's a clip from the climbing film "A Fine Line," made a few years back. One of the themes of the film is the unprecedented rise in bouldering standards in the last decade. In this clip, Daniel Woods climbs James Litz's Idaho testpiece Warpath (V14).
