Upgrading my Ship Mustang alpha to?

So i got the Mustang Alpha (Its a good littel ship fer huntin' th' loyalist)

But Now i am thinking about upgrading from it, atm ther is not mutch as our Pirate / Freelancing grp can do.

So i am thinking what ship should i upgrade to? my eyes is on Avenger stalker or Cutlass black (as we can use it as bording ship later)
