None of the other heroics give jewelry, although Hoth gives a sick snowspeeder ITV (the Secrets of Syren is superior, although you can have both and have five travel points) and the new heroics give some cool shit.  I have done Hoth, although no member of my family have done the new heroics.  My mother is unlocked for all nine heroics (leave it to a 70 year old grandma to be the power gamer of the family, at least for THIS game, my younger brother has two sons), although my younger brother and I are not unlocked for any of the three new ones, only the six old ones.  Nor do I intend to unlock myself for the three new ones as they aren't canon to the old SWG, not to mention Avatar Hardmode requires space and I'm not fond of space.  Whenever I need space, I have someone help me, lol.
