Man, there's a reason it's still there. 2-3 months ago, armed with a coathanger, a nut tool, and a stick, I also atttempted to booty this cam (yes, it is the same one). I spent 2.5 hours hanging there (on lead, no less--had to go get the coathanger). 2.5 hours, constantly working to booty this cam. Every five minutes or so, I could get it to move a couple inches, then it would overcam again in the deviously undulating crack. This continued on the order of 30 times. When it got too dark to see, I broke the stick, which had become integral in my methods. I downclimbed in shame, defeated by the shiny little red metolius range-finder cam. I treated my uncomplaining belayer to dinner in exchange for his immensely boring duty.
btw there was no quicklink on it 2 months ago, and just about every part of that crack does in fact overcam the cam, that is why it is still there.
