Hi everyone. I am stuck on a sudoku puzzle shown below. The puzzle source is the 27th sudoku problem from the September 2015 edition of the 7 Sudoku Monthly Puzzle Pack.

Code: Select all
    6     3       8  |  7   149      49    | 25     25    19
    1     5       9  |  6     3       2    |  8      7     4
    7     2       4  |  18  189       5    | 19      6     3
    ------------------+------------------------+-------------------
    58    9       7  |  48  248       3    | 25      1     6
    4     6       23 |   5    7       1    | 39    239     8
    58    1       23 |   9  268      68    |  4    235     7
    -----------------+--------------------+-------------------
    3     8       5  |   2 1469     469    |  7    49     19
    9     7       1  | 348    5      48    |  6    34      2
    2     4       6  |  13   19       7    | 139    8      5

I'll give an extra hint about Jason's XWing. Look carefully at Rows 1 and 7.
