Brilliant idea! Love how the symmetry rule plays such a big part throughout. At first it really doesn't seem like the 5 arrows will be enough to populate the grid, especially with the ambiguity over the middly digits. There is a miraclesque quality here, just like in your first puzzle.
Fantastic execution and a pretty finished result! Merry Christmas
