It gave me fits too-made a mistake early and had to restart, missed the second version of the 256 XY-Wing, and found a mistake in my original notes. In addition to the solutions mentioned, I found:
1. XY-Wing 245 pivot r9c9 setting r7c5<>2
2.three versions of W-Wing 45 in c69, all with SL on 5 in r2,r8, c7 all setting r9c6<>4
3.W-Wing on 25 in c47 SL on 2 in r7 setting r8c6 and r9c9<>5 |

I saw the W-wing also.
Otherwise, an X-wing on 5 opens up an XY-wing 2-45.
