Bounty Hunter Ships

They are filler.

Hounds Tooth gets used as a crutch for every other fleet.

Xanadu Blood is best used as a breach-buddy for Hounds Tooth but when HT is used with another faction fleet that usually weakens the lineup.

Squish 1 hits like a wet noodle until you get to its special which takes too long to get to and if used as a reinforcement it taunts which is a bad idea for such a squishy ship.

IG-2000 has more synergy with the Separatists but is optional even there.

I would say malevolence and then empire. With malevolence you have IG that synergies with separatists.

They are not as strong as they look. As a stand alone fleet they are rather blah compared to other options. There are really only a couple of reasons to go for them as a fleet.

1 - to get Han's Falcon - Not a big priority if your in a guild that gets you GET2 as your end goal will be Malevolence or Negotiator.

2 - as a passion project

But to answer your question, Endurance probably, force taunt back to HT when they get it off + protection recovery plays well. But you would have a stronger overall fleet running HT and the better Gal Republic ships.
