Hi Ron, you're right I have the footprint for both but was trying to avoid oval's if possible. The port has two plastic pins on the bottom (you can just see them) which I believe are there to align the port correctly. As the pins are so tight I wonder if this is enough to ensure correct soldering.
Regarding the soldering I guess with ovals the solder paste will do a better job filling it rather than trying to fall through. I still don't like it though, if there's not enough paste it won't fill it and there has to be more than the standard amount used on surface mount components.
