I ran the 40 point Guri build of Predator, Title, Sensor Jammer, and Authothrusters with 3x Kihraxz to a winter tournament victory... I had switched it up from Lone Wolf and ID...
Predator makes a world of difference for offense in the 'stress meta' and allows me to fly with my Kihraxzs and focus fire pretty heavily. Usually Guri is such a deterrence (poor target) because of the defense that she gets left alone, but the Kihraxz can put on some hurt before going down while Guri has free reign. There was one game where my opponent focused Guri down first with his 7x TIE swarm but not before he lost Howlrunner and 3 Academies...the Kihraxzs finished up Scourge, and the other two.
I have also used her mid PS to block aces and also hunt down stress hogs...her damage output is very high, even while stressed due to Predator and her pilot ability.
For Xizor, I would run him with Predator Autothrusters along side a few Zs or an unhinged ICT Y-Wing.
