Same as you, Marty, but in a slightly diferent order: XY (157), XY (125), XYZ (128) and then two x-wings, one on 2 and one on 5.
Good one, Danny. Thanks.

I finally had a chance to spend some time on Sudoku, and completed this puzzle in three steps; xy-wing 15-7, xy-wing -125 and a xy chain that covered half the puzzle.
