Very demanding, but possible with a lot of CE/VCE. No chain needed.

very nice pattern
shortest path for me beside CE:
initial xwing 4, the Setti 3,7,5, finally xwing 2
I find it particularly interesting that the situation in AE12,BD2 does not represent UR, although one might assume that it does.

Slightly more difficult than the B-puzzles of late, but cleanly solvable and most certainly fun. Thank you!
