help with all the power dunk moves ..........

i've seen a couple of these but i want to know which dunks from the power freestyle type let you really throw it down on somebody?

I got Lebron, and i really wanna throw it down and dunk over and on somebody . Any help whould be great.

With power dunkers (Big Ben, Shaq) you could press the FSS Trigger + Pass button.
Those dunks are pretty nasty.

Mostly centers do power dunks, I dont think any1 else can.
