Normal sudoku rules apply. Digits along an arrow must sum to the digit in the large circle at its end. Adjacent digits on a green whispers line must have a difference of five or greater. I think this puzzle is 3 stars out of 5 for difficulty for many solvers. As always, comments welcome!
Vague hint (highlight to read):
It may be helpful to often ask, "If I do this, will it break that?"

The way the whispers interacted with the arrows was very nice. 2.5/5 in my opinion. Great puzzle.
