I'm going to lean on Sterns for this. IM, ac/dc, SM, Tron, LotR & TSPP, even WPT, if you're trying to get final modes on these games, you are going to be having one hell of a hard time. I can't think of a recent stern that wasn't very brutally hard to get to the final modes on. In some cases the games may seem easy, but in the end you'll just find that you only completed about 3-4 modes.
