Trying out Zetamath's double arrow constraint again! (NOT between lines.)
Normal Sudoku rules apply. Gray lines are double arrows; the digits on each line must add to the sum of the digits in the circles on the ends. 159 rules apply: Each digit in column 1 indicates the position of 1 in its row (that is, if R3C1 is a 6, R3C6 is a 1). The same is true in columns 5 and 9 of the digits 5 and 9, respectively.
Solution code: Row 5 followed by column 8, no spaces

If I could choose "very nice" twice, I would! Enjoyed this immensely.
