Logic Masters Deutschland e.V.

Hi everyone! I'm a new setter, and this is my first puzzle on Logic Masters. Perfectly Unbalanced is an introduction to a constraint I've been experimenting with called See-Saw Lines. I hope you enjoy it, and feedback is very welcome!

Rules:

Sudoku: Place the digits 1-9 exactly once in every row, column, and 3x3 box.

See-Saw Lines: Along each gold line, the sums of adjacent pairs must alternate between less than 10 and greater than 10. No adjacent pair may sum to exactly 10. Each line may begin with either a less-than-10 pair or a greater-than-10 pair.

For example, if four consecutive cells on a line are A-B-C-D, their pair sums could follow A+B < 10, B+C > 10, C+D < 10, or the reverse.

Kropki: Digits separated by a black dot are in a 1:2 ratio, meaning one digit is twice the other. Not all possible black dots are necessarily given.
