This is the first puzzle in a series exploring lines that act as both Dutch Whispers and region sum lines, and is meant to serve as a relatively simple introduction to this constraint combination.
Rules:
Normal Sudoku rules apply.
All lines act as both Dutch Whispers lines and region sum lines.
Consecutive digits along Dutch Whispers lines must differ by at least 4.
Digits along a region sum line must add to the same total in each region the line enters.
Solution code: Row 2 followed by row 7 (18 digits no spaces)

More than 2 stars for difficulty, in my opinion.
But a nice puzzle anyway!
