Took me two to do it:
Quote:
w-wing 31
w-wing 43


Or one nice loop!
Quote:
(2)r3c6=(2-7)r3c7=(7)r2c7-(7=3)r2c5-(3=1)r4c5-(1)r4c9=(1-6)r2c9=(6-2)r2c4=(2)r3c6
=> r3c6=2

I had an XYZ 1-34, then a hard to spot (for me) W 3-4.

I can spot w-wings quicker than xy-wings or even harder xyz-wings. I like taking stong links and connecting them. Most difficult for me is ALS and sets. I guess we are all different. I am into loops right now.

I started with two XYZ-Wings and a useless multi-coloring on 1. Then I was stuck big time until I noticed a triple in c7 which had been sitting there. That opened up enough to expose a puzzle-ending W-Wing on 34.
