Hi Jump Kick has amazing power, and even if the opponent uses Protect, you should be able to predict that.
A weaker alternative is Brick Break, as it breaks screens, as well as 75 base power. Drain Punch works well too. 75 base power is pretty good for UU, especially with the extra effect. Although really, Hi Jump Kick is better.
Those are pretty much the only STAB moves that you would want. Low Sweep is an option if you want, a literal "Low Sweep." But use Hi Jump Kick. Try to predict the Protects.
