Kiba is way too much of an offensive juggernaut for Shino to handle once he enters Twin or Triple headed wolf. It's a horrible match-up for Shino.
Only argument i could see would be bug clones or something like that.
Kiba is easily a whole lot faster, so he'll just mow down each and every clown Shino presence. Can't think of a single way Shino can win once Kiba pulls out his big guns.
I'm favoring Shino here.
