Am I missing something or can this only be solved by either of the (admittedly straightforward) XY Wings?

126 on R3C2,R5C2,R5C6
136 on R1C3,R3C2,R6C3

Code:

+-------------+-----------+-------+
| 123 4   13  | 12 9   5  | 7 6 8 |
| 9   5   8   | 4  6   7  | 3 1 2 |
| 6   12  7   | 8  123 23 | 9 5 4 |
+-------------+-----------+-------+
| 35  8   2   | 9  35  4  | 6 7 1 |
| 15  16  9   | 7  25  26 | 8 4 3 |
| 4   7   36  | 36 8   1  | 2 9 5 |
+-------------+-----------+-------+
| 7   9   5   | 12 12  8  | 4 3 6 |
| 23  236 4   | 5  7   36 | 1 8 9 |
| 8   136 136 | 36 4   9  | 5 2 7 |
+-------------+-----------+-------+

Hi Hugh! I noticed there are LC's on 3's in col 2 (-3r8c1,r9c3) which looks like it solves it!
