I'm around 5'11" and really struggled to get solid beta. Now have the climb nailed, and it's one of my favourites. A very fun / exciting lead. Didn't feel like 10c as the guidebook suggests if you're short, but definitely not 5.9. Stick clip is highly recommended!
Ditto the recommendation to stick clip the first bolt or bring a crash pad. Even for tall people the bottom is bouldery, with a bad landing. With practice I could see it feeling like a 5.9 (if you're tall), but definitely more like a 10a. The deke out left is exciting!
It's hard to give it a real good grade since there's some pretty hard moves near the bottom if you can't reach through them. Guidebook says 10c if you're under 6 feet and really it could be that but the rest of the climb definitely feels closer to 10a so I dunno. Either way pretty fun climb but don't try to put your beginner friends on it for a chill 5.9
A bit reachy if you are under 6'. Al suggests 5.10a for shorter folk. Consider stick clipping first bolt or bringing a crash pad to the firewall... decking here would suck - lots of uneven ground and rocks. Otherwise, a fun climb.
