This is a great move for keeping your defender guessing and also can result in ankle breaker animations.
This year when doing the momentum dribble you can hold RT/R2 the entire time. This move works with both hands but you need to pay attention to which hand you are dribbling with. When the ball is in your right hand start with a Right 7. Give an extremely short pause, less than a second, then Left 8. Finally, follow that with a Right 4 to trigger the between the legs animation.
