Its not worth it to make a big hit anymore. If any part of your shoulder gets near their head its a major, and especially so if the guy decides to hold his head and stay down on the ice. You can't tell me there aren't kids that head out on the ice with the intention of drawing majors if they are hit on the wall. Turn late, head into boards, get up slow. Half the d men actually grab guys as they are checking them into the end wall and holding them up so they don't flail into the wall and boom there is your major penalty.
