Only did this route. Had a severely sprained ankle, seemed a little stiff for this grade as crux was reach dependent and required some good footwork. Prob worth UK grade 6a or 6a+ which is 5.10b ish.
May be different at full fitness but small crimps and fine footwork seemd too hard for 5.9
It is also worth pointing out to all others in this forum that a popular route mentioned in a 10 year old guidebook will be significantly different tofay than it was when first climbed or bolted. Sandstone climbs always change their character over time due to type of rock.
Popular routes in the UK are updated over the years as they become polished, shed holds or the holds deteriorate.
Bear this in mind when comparing actual grade to grade in guidebook.
Check the published date.
That said - I only did one climb !!
P.S I climbed 5.11d indoors at Berkeley so do have something to base my opinion on.
