Steven Black's list sources from multiple lists as well. Checking out your lie-to-me project, there is actually a lot of overlap between what Steven is already pulling in and what you are getting. Looks like one of your sources 'palevotracker.abuse.ch' is discontinued and responds with a 500.
OpenVPN uses about 20% of mine, so I guess it really is a step forward.
