Stitched Lines

Thanks to NicoD's puzzle "Serpentine" as the inspiration for the line pattern. Normal Sudoku rules apply. ROTATIONAL SYMMETRY- Cells 180 degrees apart in the puzzle sum to 10. KILLER CAGE- Numbers in the cage sum to the number in the top left corner of the cage. GERMAN WHISPERS LINES- Numbers on green lines are at least 5 apart from their neighbors on the line. RENBAN(+)- Numbers on purple lines are each a set of non-repeating, consecutive numbers, in any order. Also, each RENBAN line contains either a 1 or 9. KROPKI PAIRS- Numbers with a white dot between them are consecutive. Numbers with a black dot between them are in a ratio of 2:1. Not all possible dots are shown.
