Or maybe this seems better:

Sigma squadron + Sensor Jammer + Intelligent agent + Stygium (32)

Shadow squadron + Sensor Jammer + Intelligent agent + Stygium (34)

Shadow squadron + Sensor Jammer + Intelligent agent + Stygium (34)

Echo + Veteran Instincts + Recon Specialist + Advanced Cloaking Device + Fire Control System (40)

Sigma + Advanced Sensors + Stygium (30)

Sigma + Advanced Sensors + Stygium (30)

Of course I actually want to try Whisper and Echo escorting a cheap Doom Shuttle.

Im thinking

Echo+ Vet instincts, recon specialist, particle accelerator

2x (skill 5 pilots) with recon specialist, particle accelerator

The extreme maneuvering options this ship presents means very often you will be able to keep a target in your sights while leaving theirs. The extra points on higher pilot skill is worth it, as you will move after tie swarms and 4 ship rebel builds. Higher skill builds mitigate this, but they have 12 shots coming their way a turn, so you can still win it. Falcons, which are being sold as the counter to this list, will get hit hard with 3x4 attack dice, especially with focus

The whole cloaking thing is cool, it really is. But over emphasis on cloaking is a red herring. What these ships bring is the best base firepower with the best base maneuvering options in the game. Nothing is close to as unpredictable as these are. So I think cloaking should be used to approach the enemy fleet safely. Have the 2 skill 5 guys deploy across from them and then echo fly as a solo flanker. Make the joust as awkward for them as possible, ideally using your (probably) superior firepower to nuke an enemy ship or 2 before they get a chance to shoot. After that you win in any furball situation. Especially because you have incredibly potential to get behind ships while keeping them in your sights, greatly increasing your chances for a 5 dice attack at range 1. I don't know the math, but I don't want to see what 5 attacks with focus does to a tie fighter.

Shadow + advanced cloak + FCS x3
