There's a couple of points on Pintle LHV that may spit off a grade 16 leader. Around the bolt is not one I would expect.
What really concerned me looking at it on the weekend was the damage to the flake, and based on Andrew's comments this was deliberate (though not by him). Climbing with some thought for the conditions seems a useful skill, rather than battering off a section because it's a bit hollow. There's hanging and detached flakes aplenty at Buffalo (Banana Blase has a good one as well), and climbing them delicately is part of the experience to me (despite the fear it gives me!).
