Probably found the same path as duke... 2 slightly different 68s.
EDIT: 3 weeks later I finally solve it. Thanks to Devildude1 for the inspiration. There's a 2-off path that is extremely convincing, but the real path makes a lot of sense. Even on the correct path, there is a clever way to save the last two moves.
5 star difficulty for me, but need to dock a star for the wasted space.
