Walk around the cages

Normal Sudoku rules apply. In a killer cage digits do not repeat. Digits on an arrow sum to the digit in the circle where the arrow emerges from. Digits joined by a V sum to 5. Digits joined by an X sum to 10. (Not all Vs and Xs are given.) Digits joined by a black dot have a 1:2 ratio. Digits joined by a white dot are consecutive. (Not all black and white dots are given.)
