So after getting my butt somewhat kicked at a tournament I decided it's once again time to play with Twin Shadows for a bit, and chose to play with the list that got 1st place in UK system open swiss, which goes like this:

Pursuit Craft: •Ketsu Onyo (53)
Gyroscopic Targeting (2)
•Shadow Caster (3)
Outmaneuver (3)
•Dengar (3)
Glitterstim (2)
Glitterstim (2)

Pursuit Craft: •Asajj Ventress (47)
Gyroscopic Targeting (2)
Push the Limit (3)
•Latts Razzi (2)
Glitterstim (2)
Rigged Cargo Chute (1)

Total: 100/100

I only played two games with it and lost, the first due to dice, the second because I threw Ventress off the mat. Despite this, I enjoy playing it and realized just how customizable these twin shadows lists can be, so I am making this post for everyone to share their double lancers lists, I'll start:

Pursuit Craft: •Ketsu Onyo (53)
Counter-Measures (3)
•Shadow Caster (3)
Expertise (4)
•Dengar (3)
Scavenger Crane (2)

Pursuit Craft: •Asajj Ventress (47)
Counter-Measures (3)
Push the Limit (3)
•Latts Razzi (2)
Scavenger Crane (2)

Total: 100/100

Lw, gyro, latz, double stims asajj

Fearlessness, EU, dengar, double stims Ketsu w/title

Been thinking about it for a while and I don't see getting a better-than-four-dice-primary as a bad deal. Rey gets SO much praise for Finn's die, after all and that's worse (though far easier to trigger obviously)

Plus, if you want to ketsus ability, you're probably going to block the enemy (hence EU) and roll them out of b2b to shoot them in the face

And when you swap arc for mid/late game straffing, fearlessness still works out of your mobile

Definitely don't think the issue sounded like you need to tweak the list.....

Your second list is very good.

I firmly believe that Expertise/Dengar/Title should be glued to Ketsu, and PTL/Latts should be glued to Asajj - so you have that down. And its really good. As for the rest, any combos of countermeasures/glitter/scav crane is strong - experiment with different combos.
