Again, this puzzle was not truly a VH; basics took more time than finding the first normal XY-wing to finish it off.

I did not find a single wing solution to work for me. Below is where I arrived after basics. 2 xy wings (including one of yours) is what I (thought I) needed.
On second look, the 1-2-6 xy wing resolves it entirely. My other xy wing was 1-2-5.

| 124 3 12 | 24 6 7 | 8 5 9 |

| 7 26 4 | 8 29 1 | 5 69 3 |
| 3 125 125 | 46 29 46 | 7 19 8 |
| 9 8 16 | 7 3 5 | 2 16 4 |
+-------------+----------+---------+
| 56 59 7 | 1 4 3 | 69 8 2 |
| 24 24 3 | 5 8 69 | 69 7 1 |
| 16 19 8 | 69 7 2 | 3 4 5 |
