Thanks Rubyw and Missspacey,
That's all really helpful. One of my examiners is also very prolific, so just as I thought I was nearing the end of the thesis, I find I have a lot of reading to do!
I think they are both nice people, so touch wood they won't be nasty for the sake of it.
In fact, if my thesis is OK and I'm feeling confident, I think I should almost enjoy a viva with those two!
I've probably spoken too soon...
Thanks again.

I'm very shocked and sorry to hear these stories, so was wondering if I could ask practical advice for trying to preempt these viva issues. I suppose theoretical approaches might be more flexible for social sciences than methodologies for science (? - I'm the former by the way), but I was wondering how much you should theoretically 'suck up' to your viva examiners. If you know that their approaches differ from yours, should you modify your thesis accordingly? Especially if the examiners are very well established academics, whose line you are not towing? Or at least throw in some more of their work? Or might this annoy examiners? Thanks!
