This is a great thread! I have seen fins that bent before and not cause that much reduction in power. Thinking Coley might be right about them holding the pins in. Might be able to pry on them some and get to ease up on the pressure? Anyway if ya get the the new ones the saw out method would be great. I am wondering if the pin itself could be pranged in some way. Might be good to get a new straight one just in case.
