No logical steps found part 5..my brain hurts

Normal sudoku rules apply. Place the digits 1-9 once each in every row, column and 3x3 box. Digits along a grey line read the same forwards as backwards. Digits in a dotted cage without repeat sum to the total given in the top left corner of the cage. Adjacent digits along a green line must differ by at least 6. Cells separated by a black dot has one digit double the other (1:2 ratio). Cells separated by a white dot are consecutive. Clues outside the grid sum the digits along the indicated diagonal, digits may repeat. No negative constraints.
