After carefull elemination you discover that A6 can`t be 9 if A2 is 4 - with setti 2 --> HJ6 must be low!

No guesses needed for the weekly. After CE, virtual wings solve F3. Then Setti 6. A very short HC on A5-F5 hi/lo leads to a UR consideration in cols 8 and 9 and clears hi/lo in col. 5. Then Setti 3, Settis 5,6,7, and finally Setti 8.

I would love an explanation of virtual wings

By virtual wings I meant that you don't know yet where the wings will exactly be, but that they must be in the two respective cols or rows. Two of these made F3 a single.
