Punisher is bad, no doubt. However, a few of these builds have been absolutely terrifying and have really gotten the job done.
Deathrain: Enhanced scopes, cluster mines(x2 if you want but 1 is fine), Flechette Torpedoes, and Extra munitions, Long range scanners or Twin ion engine mk 2 are also optional.
This little bomber caused havoc in many a game, passing around stress and littering the field with bombs. His ability to bomb out the front and move first in addition to boost makes him a great blocker and guarantees hits with bombs on many ships. VCX or falcon, "Here, catch!" take 6 unavoidable attack die of damage, which usually works out to 2 hits and a critical before attacking. Flechettes can be really good when another ship (Lambda or Phantom) has sensor jammers on it. Very good control ship.e
Redline: Cluster missiles, Your choice of (Concussion missiles, Proton Torpedoes, or Plasma Torpedoes), Extra munitions, Fire Control Systems, Long Range Scanners, and ion bomb(optional)
Redline hits like a truck. Using ion bombs keeps other ships off of him if he is being tailed, with clusters and a range 2-3 4 die attack he has all ranges covered and his double target lock often keeps you from the general problem of long range scanners of lacking a TL on the second round of combat. I have watched X7's go down to this build multiple times. Unfortunately, keeping him alive can be problematic, so make sure you fly him with a defensiveness that allows for safer shots that your enemy won't want to trade with.
