I played yesterday twice, two victory, very funny, I love quadjumpers:

4Lom Guri Quad Quad (198/200)
===================
G-1A Starfighter: 4-LOM (49 + 14)
+ Crack Shot (1)
+ Advanced Sensors (8)
+ 0-0-0 (3)
+ Mist Hunter (2)
StarViper: Guri (62 + 9)
+ Crack Shot (1)
+ Advanced Sensors (8)
Quadjumper: Jakku Gunrunner (28 + 4)
+ Feedback Array (4)
Quadjumper: Jakku Gunrunner (28 + 4)
+ Feedback Array (4)

Would be better with pattern analyzer on quadjumpers but I don't have the card yet.

Proxy PA for the Quads, lose the Cracks for Predator on Guri!

Certainly Pattern Analyzer for Quadjumpers! If not, maybe Deadman's Switch. Your opponent might be more reluctant to kill one if they'll blow up too. This can give them a bit more time to get work in. There are obvious potential drawbacks to DMS, however.

Another thought is Trick Shot on 4-LOM and Guri... Both have pre-move barrel rolls they can access, and you've got Quadjumpers tossing people into awkward places, so I feel like they've got a better capacity to pull off obstructed shots than a lot of other ships.

Yes, pattern analyzer could be the perfect fit.

DMS was one of my option, but I don't like drawback, yesterday would have been positive for my challenger and not for me.

I will try predator on Guri

You may want to spend those 8 feedback array points elsewhere. Those tugboats can put down some damage on their own, especially at close range and you want to keep them mobile with their movement options..

Consider Lone Wolf (4) on Guri if you're flying her away from your main pack or the Virago title (10), which comes with an extra shield.

There's also a nasty Outmanuever (6) + Adv. Proton Torpedoes (6) combo to consider on Guri. (Drop Guri Crack Shot and 4-LOM 0-0-0 for this I'd think).
