Sounds/looks great. KE F is pretty nice as well, so don't worry if CX doesn't open.
True, I'd just prefer to use 67.5k AA than 80k UR. I'll need to keep extending the hold, so if I can do that or someone gives be free UR I'll just stick with KE.
Also, from pix it looks like the foot well on F is a lot wider than on CX F. Is CX F restrictive down there? I'm comparing it to LH J on the 747-8 which has a really restrictive foot well.
