Why do you say that Sir? Is it because you feel that you wont be able to achieve a release? If so I understand your comment.
But! I urge you to analyze the purpose of the crashing wings beyond attacking the forearms. It is not meant to achieve release at this point, If anything this would allow the attacker to disengage... and we want him right were he is.
The purpose of the crashing wings is to disable the arms momentarily as you step around into the lifting elbow, and simultaneously canceling zones that effect height, width and depth, thus allowing for greater contact manipulation and a more controlled aggressive offense. Attacking the attack.
