The other puzzle seemed to be a success. I hope this one is as well.

As part of my first pass, I used two URs, a xyz-wing and a xy-wing. However, I made a second pass and determined that both URs were not necessary; just the xyz-wing followed by the xy-wing as already noted by storm_norm.

Hint:
Quote:
xyz-wing <126> in box <9> and row <7> and xy-wing <127> with pivot in r3c1
