haha-face off tut would be good.
i've used(and had this move used on me) and it's effective if you're fast enough.
if my reaction time is better than yours and you're trying to pick you stick up and push it under mine, and all im trying to do is turn my head 90 degrees (start to end of clamp) then you're out of position to block my rake.
also practice trying to keep your head as close to the ball as possible, incase someone else tries to jam while you are, the lower head always wins.
