Should you run a turbolaser on BTAvenger, and if so, which one?
My impressions, ranked best to worst:
QBTs: Helps Leading Shots out big time, if you can maintain a lower speed. Side arc and long range rerolls are nice.
XX-9s: I feel like these have serious potential for once. You're highly likely to get in 2 or more hull damage with a crit on your superturn, and big targets stand a decent chance of not quite dying. A 30% chance of Structural Damage could help.
Needa/TRCs: Takes the officer spot, so no Tua + ECMs/SFO. A guaranteed double hit at any range and any arc is great, though. Plus you won't need that evade up close. Expensive at 9 points.
Empty: It does save points!
XI7s: Amazing in general, slightly less useful here. Sure, they'll get damage to stick at long/medium range, but your opponent isn't really going to be redirecting when it matters most anyway. An extra TIE squadron might be better.
Spinal Armament: An extra red die is an extra red die. Even if it's not cheap.
Slaved Turrets: Is it worth saving three points? At least it works for the sides...
DTTs: Maybe as a source of dice mitigation?
Enhanced Armament: Does nothing for your front arc. Expensive, but not reliable.
H9s: Good on a normal ISD1, but kinda contradicts the point of BTs, at least at close range. Expensive at 8 points.
QTCs: Same as H9s, but more so.
HTTs: Well, you wouldn't use them normally, and they do even less now. So no.
Obviously these depend on the build, and I've never tried QTCs on Avenger, so I can't speak with certainty.
What are your opinions? Recollections of a time when a turbolaser really helped? Meta-specific choices?
