Level 3 grip is fun
If you grip them, hold them up, and let go and use force push really fast, they'll fly over your head, occasionally hitting you and looking as if Kyle parried the body over his head.
Push works well too as your able to launch the enemy directly above you.
You can push Thermal Detonators around too.
While Im at it, you can flip stormies with grip. Grab a stormie, roll backwards and look up at the same time. When you get straight up, let go (dont stop, else he will just fall down) and he'll go flying right over you more than likely dieing from the fall. You can also do this trick in the air with level 3 force jump by grabbing the stormie as you ascend and toss him up as you reach your peak. Major hang time. Heck you can even push him upwards from there if you want.
