Dotted Region Sum Lines 2 / Gestrichelte Region Summenlinien 2

Normal sudoku rules apply. The digits along a blue region sum line must have the same sum in each 3x3 box entered by the line. Neighboring digits marked with a white Kropki dot are consecutive. Neighboring digits marked with a black Kropki dot have a 2 to 1 ratio. Not all dots are given. I think this puzzle is 1.5 stars out of 5 for difficulty for many solvers. As always, comments welcome. Thanks!

The first 1/4 or so of the solving process was genious with digits being eliminated as if by magic (or a very well setup grid) ... then it gets tough. I needed lots of pencilmarks to figure out the rest. :P
** Thanks very much for the feedback and solve!
