Pete,
In the County there are few cracks that are really 'offwidth' in that the use of offwidth technique is a prerequisite for success. Cowboy Up is a flared crack (and that's the easy bit). The relatively short length of many of our cracks lends them to a 'shit or bust' sprint approach that avoids the slow torture of off width technique.
Most can be climbed by using a combination of face climbing around the edges (or inside), laybacking or laying off.
That said, wider cracks include; Green Crack, Hanging Crack, and Slab Crack at Bowden, The majority of the cracks at Ravensheugh. Long Layback at Simonside can provide a worthy tussle if you choose to jam it (as of course would OH Crack at Bowden were you to climb the crack at the top!)
I can only think of one unclimbed feature in the County that would demand the sort of sustained, inverted 'Wyde' techniques seen employed in the US...............
