Interesting fact about Roseland Rob. Now there is even less reason for that pin.
Seth, I'm aware that we're talking about a lot of pins. I think every one you mentioned should go. (Well, I don't have a good image of the pin on Morning After.) Mind you, I'm not speaking of removing any of them, just that they shouldn't be replaced when they deteriorate sufficiently.
Many people are already placing cams next to pins to back them up because they don't trust the pins (a wise perspective). So why not dispense with them altogether once they fall out?
