Mountains are definitely tricky when it comes to fencing. Without exactly the right equipment, you can end up with a poor fencing job and dangerous too. I feel your pain!! We barely have a place on our property that is flat. And if it is flat, there are probably rocks. But oh, do we love the mountain life.
I would take down the old fence, if you are able. It may provide a 2nd line of defense, but it also may become quite the hazard and keep you from accessing both sides of your new fence for repairs, etc. If you can't access the space between, that's definitely a mess. Stuff will grow in there, become a tangled mess, and if you have my luck a chicken will inevitably get into that area and need rescuing some day. Clean fence lines make for stronger, longer lived fences.
I agree about keeping woods, I love our tree lines for privacy. When we continue our perimeter fencing, we will take down a bunch of cherry trees (poisonous to everything we keep here, anyhow) and clear a lot of autumn olive. It will be sad to see it all go, but we have a big field between us and our neighbors on that side. And, there again, we need access to both sides of the fence for any repairs. Can't have our little 25-30lb calves squeak through in a place we can't see.
My motto is farm smarter, not harder. We do our best to do our best the first time, so we don't have to constantly fix things. If we are not able to do it right the first time, at the very least we learn from our mistakes.
