It's a halfling. I mean, I can go into detail how they make pretty good rogues or how strongheart is the best of all subraces, but it's not going to change the LA. +0 for standard.
Skill bonuses have been switched around and are slightly better now. Truly revolutionary. +0.
Once more, the underground version of a race is a very good pick. Darkvision, stonecunning, and more in exchange for mostly useless skills (seriously: who needs jump and climb after level 6 or so?). Worth playing if you ever need a SRD-only rogue or something. +0 LA.
