Michelle, I have no experience myself (apart from the fact that I was a vaginal breech birth all those years ago!) but my gf has had two sets of twins, both times one was breech.

She had an epidural both times because her Dr was worried that if he needed to manipulate the second baby a great deal to get them out, it would be quite painful for her. The second time she really didn't want an epidural, so they came to the compromise that it would be put in, but not turned on until they assessed whether she needed it or not. In the end she did have it, but enjoyed most of her labour without any pain relief.

I'm no expert, but I think obs are more likely to deliver a twin breech than a singleton? Perhaps because twins are usually preterm and therefore smaller? Not sure. Her first breech baby was born at 34 weeks and he was only 4lb something, the second was her third daughter born at 36 weeks 5 days and she was heavier at almost 6lb.
