Rotationally Symmetric Constraints

Normal sudoku rules apply. Place the digits 1 - 9 once in every row, column and box.
Rotational Sums of 10: All digits in the grid have a 180 degree rotational opposite. Every digit and its rotational opposite add to 10. Eg. R1C2 and R9C8 must add to 10. Eg. R5C4 and R5C6 must add to 10.
Killer Cages: Digits in cages cannot repeat and must sum to the total shown.
Palindrome: Digits on the grey line must read the same from both ends.
Kropki Dots: Digits separated by a white dot are consecutive. Digits separated by a black dot are in a 1:2 ratio. Not all dots are given.

This was extremely fun to solve. I think the break in is nigh on 2 stars, but still very intuitive.
RailMan: Thank you

This is awesome, but I think the breakin is harder than one star—super interesting though!
RailMan: Thank you. I also thought it would be 2*
