TS Kiba's strongest point is that Akamaru will follow an opponent even after they sub sometimes. So they can sub and be hit instantly, allowing for a safe combo cancel (no risk of getting a rasengan to the face afterward).
So in short: TS Kiba is best used for combos.
As for supports, PTS Kiba by himself, on attack, is pretty deadly. Plus, two fang over fangs simultaneously will always annihilate guards.
Any time I use Kiba, I just use Shino and Hinata as supports. Kurenai is an awful support so don't bother. --- We're here, we like beer, get used to it!
