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.

Code:

+-------------+----------+---------+
| 8   46  69  | 3  5  49 | 1  2  7 |
| 25  7   259 | 29 1  8  | 4  3  6 |
| 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 |
+-------------+----------+---------+

The xyz wing 124 in box 1 finished it off for me.

This message board shows---at my site---that there is only one reply to this thread, when in fact there are about 6 replies. What's up with that?
