Well, if there was a teetering pink tricam placement, where was it? I looked. Pink, white, black, I didn't get one, teetering or not.
I was speaking hypothetically here lol, and I really wish I had some specific gear beta for you, but I don't. I'm guessing the reason you couldn't find any is because there isn't any to find ... and no big secret or conspiracy going on. One commenter on MP mentioned being 15' over a white tricam, and a few others mentioned R conditions (over aid type pieces). I certainly wouldn't call it a failure on your part ... you did successfully climb it, didn't you?
