My driver boom and sail is huge and it is connected without any rubber shock support. It takes a pretty good beating on some of the tacks, most noteably the ones that go from running to reaching when I don't tighten first. I have had no failures...yet
As for the brig running down wind, square masted ships are known for their ability to do that and are much better at it than other types.
