Because I only just realized that the Aggressor has two cannon slots (D'oh!) and the Synced Laser Cannon loves it some calculate tokens.

I try to spend most of my theorycrafting time in Hyperspace but sometimes you just gotta.

IG-88C (63)
Marksmanship (1)
Synced Laser Cannons (6)
IG-2000 (1)

Ship total: 71 Half Points: 36 Threshold: 4

IG-88B (62)
Marksmanship (1)
Synced Laser Cannons (6)
IG-2000 (1)

Ship total: 70 Half Points: 35 Threshold: 4

4-LOM (49)
Elusive (3)
IG-88D (3)
Mist Hunter (1)
Autoblasters (3)

Ship total: 59 Half Points: 30 Threshold: 5

Total: 200

I played a similar list to this before Nom Lumb came out (Ion Cannons back then). 4-LOM really doesn't get anything out of IG-C's abiliity, so I'd recommend dropping Elusive and changing to IG-88A for the calculate sharing. It'll help ensure that the IGs have calculate for their sync'd cannons and give 4-LOM both abilities.

Good stuff!
