If you decide to go for it I wish you all the luck in the world. Jza84 got through pretty much unscathed, and you very likely would as well I think. All I'd say is that you need to be absolutely certain that on the off-chance it didn't go the right way you'd still be here doing what you're doing now. Unless you've been through the RfA mincer it's difficult to appreciate just how much of an ego bruiser it can be.
