I liked the combination of finned x-wings on 5.

Code:

*-----------------------------------------------------------*
| 148 3 148 | 124 5 7 | 289 6 289 |
| 1468 5 1468 | 124 12 9 | 28 7 3 |
| 2 7 9 | 3 8 6 | 1 4 5 |
|-------------------+-------------------+-------------------|
| 18 4 158 | 9 7 258$ | 3 25 6 |
| 78 9 578 | 6 3 258$ | 4 1 28 |
| 3 6 2 | 15# 4 158@ | 578@ 9 78 |
|-------------------+-------------------+-------------------|
| 69 2 3 | 7 19 15@ | 569@ 8 4 |
| 5 1 67 | 8 29 4 | 2679 3 279 |
| 479 8 47 | 25 6 3 | 79 25 1 |
*-----------------------------------------------------------*

Look at the 5's in r67c67 marked @.

First view them as a row x-wing with a fin in r6c4 marked # that deletes 5 inr45c6.
Now look at the group of four cells as a column x-wing with a double fin in r45c6 marked $ that deletes 5 in r6c4.
Each pattern deletes the fin of the other pattern. FUN!

Either view completes the puzzle.
