In reply to balmybaldwin: It's really interesting/worrying isn't it? I read the edelrid recall earlier - I don't remember anything quite like this before; in that it seems that an entire class of safety gear, regardless of manufacturer, isn't really safe. It would be a bit like if they said ALL cams don't work (well, fortunately enough of us have fallen off onto them to know that one isn't the case!).
Never done a VF, but always wanted to take my kids on one as it seemed an exciting but "safe" thing to do!
