am I cutting into the wake wrong?

Been riding with this one dude for a couple weeks he is trying to tell me that I am doing my wake to wakes all wrong..But Ive never had a problem. I go out of the wake (not far outside the wake) keep the handle low and close to my hip, bend my knees and stand tall at the wake..Now he is telling me that I shouldnt be bending my knees at all when Im cutting in the wake and should go in straight legged?I tried going in straight legged and there is no way to get enough speed and it just feels foreign.. I stand tall at the top of the wake, and from pictures i get plenty of air. Just curious..all i videos ive seen pros def bend their knees..sorry for no pics thanks for the help
