When its all said and done, I feel like UI is going to be something Goku doesn't like or use because he feels like its not him or his actually powers. basically like he has no control over the fight and his body is just doing stuff which really isn't goku's style.
He lives for the fight and to get stronger, if his body is just doing stuff on its own and no thought from him is really going into it....yeah that's a wrap for UI outside of emergencies or to seal a victory.
He might try and put his own twist on UI though.
