I'd rate this at about 10c. The only way this could be G rated is if you can reach the first clip from the ledge. Difficult and delicate moves on thin slab before the first bolt. Pulling over the roof is tricky as well a fall here would really suck! If you're a solid 10c leader, this is a fun route. If you get on this thinking it's a 10a, you're in for some bad surprises.
