 Another phantastic challenge. Chainfree. After 5 solved cells we used a couple of Settis, later a combined Setti to decide hi/lo in D. Many thanks, hepa, and a nice start into december for everyone!

 @kris: I think after 5 solved cells and several settis the setti results helped with col 4.

Thank you BP (and of course hepa), finally did it with a bunch of settis, sometimes I suffer from temporary blindness ... but it was still quite demanding.

 Amazing puzzle, it's all about uniqueness. Step by step, I found seven URs. No chains, no guesses.

sorry for the spoiler - but difficult as it seams, and 4 in the center cross might help to speed up things

 Very nice one, BX Power. At the end I used a SI to decide that G3 is not 2.
