This puzzle is the latest collaboration between myself and Nordy.

Rules:

Normal Sudoku rules apply: place the digits 1-9 in every row, column, and 3x3 box.

All lines are Region Sum Lines: 3x3 box borders divide each line into segments with the same sum. Different lines may have different sums.

Additionally, every line segment within a 3x3 box has a secondary line type: either German Whispers or Renban.

-- German Whispers: adjacent digits along the line must have a difference of at least 5.

-- Renban: the line consists of a set of non-repeating consecutive digits in any order.

Every time a line crosses a 3x3 box border, the secondary line type changes from German Whisper to Renban or vice versa.
