Seems like the place to mention this, when we were coming off Costanoan the other day the right side hanger at the top of pitch 3 was flexing inwards when we weighted it on rappel. Maybe there's a Pinnacles friendly way to rappel or something that we missed. But the hanger was definitely flexing the way we set it up. Oh, and just so it's clear, not the flange of the hanger flexing but the whole bolt, hanger, and everything.
Definitely the place to mention it.
The only thing that sticks with me is your phrase "the way we set it up".
Isn't that anchor just rappel rings you can thread? There should only be one way to thread it.
I can take a look at it when I get back to the park.
If you carry a camera - it would be really helpful to take a picture of anything in question so I (and other rebolting-experienced folks on here) can see exactly what types of bolts and hardware are being discussed.
Here is an older pic I have of that anchor. The rappel bolts were placed way too far apart for rappel rings - which puts a lot of inward force on the anchor and may act to loosen the bolts over time. The amount of chain needed for that spread would be insane. It would be easier to just move one of the bolts or couple one long chain from the middle bolt with the right bolt's rings. I am guessing it was the sleeve bolt (rightmost) that was flexing. In the interim (of me getting out there), if someone is spooked by the flexing - they can always leave something on the middle bolt to tie it in with the other two.

thanks,
