Hi Scooby
I'm still waiting for my baby so my two cents may not be worth a great deal. But I think that you have done all the research and looked at all the risks, you have to ask yourself which risks you feel you can live with this time around. All the options have risks and downsides, and you have to decide which option you can feel the most comfortable and safe with.
Personally (while as I said I don't have personal experience yet) this is one of my worst birth fears, so if it was me in your shoes, I think I would choose the cs. That is just what I think would make me feel safer if I was in your position.
Ask yourself what you think you can feel safe with, and then don't let anyone sway you. I have seen some of your other threads get hijacked with the whole cs v vb debate and I'm sorry people can't seem to understand what you're asking.
but I think you're very brave and I wish you all the best with whatever you decide.
