I also have the Park CCP-2 . I never found a crank I could not get off with it. When I was flipping bikes 700+ I must have done at least 100.
Yesterday I was going to remove the BB on a 92 Cannondale I just got. I forgot about the washer for a few minutes and then it dawned on me to remove the washer.
It was the tightest crank I had seen in years. I needed a 14" bar on it.
