 Great challenge. Tough but chainfree. In addition to Settis and VCE I used a couple of URs. Thank you, hepa!

 Really tough, like BP, with one UR. Eliminations on the right side were essential for me.

Very nice - no UR needed, two HC (even for me :-) for 1. Hi/Lo in G and 2. ascertaining the X-Wing in CJ89.

 I always try to solve the str8ts in a specific order based on the difficulty of the solution method (at least for me).
First comes CE, then VCE, then I try Settis, furthermore I look for UR's or fish, and finally complicated methods such as y-wings or combined Settis or similar.

In this respect, the xwing was out of the question for me in the first step :)

 No´really good idea. Needed several chains on 1s and 2s in the diagonals.(And, accidentially, always started with the false assumptions. Thus more than 2 hours.)

A little help to move it forward. J9 is 67. E2 is 69. If E2 is 9 then b2 is 67. If e2 is 6 then a1 is 67. Either way all the 67 can be removed from d4 to h8 diagonal.
