The second doctor has the most prmising plan IMO. You most likely do not need a c-section. Doctors today are very much into surgery. Remember OB/GYNs are surgeons so they are going to lean toward surgery, especially the younger ones. Have you seen "The Business of Being Born" yet? If not I highly suggest watching that to get a better understanding of how things are in our society surrounding the birth process.
My doctor knows if he even suggested a c-section to me I'd probably have him in a headlock in two seconds flat. I have made myself very clear about going completely natural. Honestly, your baby is going to come out regardless of how big it is. There are things that can be done besides c-section to help things along.
