For me, it was 3 wings: W; M; and Sashimi X.

Coloring being my method of choice for the moment, I started with:

- coloring
on 4 (a.k.a kites) removes 4 from r7c4,r7c7,r9c4
on 5 (again a kite) removes 5 from r9c4
on 4 again (kite) removes 4 from r9c4

- w-wing(45-45) "w" r7c6,r9c8 via strong link in 4 (box 7)
removes 5 from r7c7,r7c9,r9c6

and extended m-wing "m" (9) r4c2,r9c9 "m" via "*" (6):r9c2-r9c4.
Removed 9 from cell(s) r4c9
Code:

+--------------------------+--------------------------+--------------------------+
| 46      5       1        | 48      9       3        | 68      7       2        |
| 8       3       2        | 45      6       7        | 1       9       45       |
| 46      7       9        | 1458    12      2458     | 68      45      3        |
+--------------------------+--------------------------+--------------------------+
| 5       69m     8        | 2       4       1        | 79      3       67-9     |
| 3       1       46       | 7       8       69       | 459     2       4569     |
| 2       469     7        | 3       5       69       | 49      1       8        |
+--------------------------+--------------------------+--------------------------+
| 9       2       4w6      | 156     13      45w      | 3-57    8       4-57     |
| 7       8       5        | 49      23      24       | 349     6       1        |
| 1       4w6*    3        | 6*89#   7       4-58     | 2       45w     459m     |
+--------------------------+--------------------------+--------------------------+


And finally:
- multi-coloring (4) removes 4 from r9c9 and r9c8 (plus many others ...)

I can't get my brain to think sashimi yet ...
