over time, i have pretty much abandoned wing play because i cannot put away crosses to save my life. my attempts at heading always go sailing over the bar or WAY off the mark. i know i am not overpowering as i tap once the ball nears the head, but am i doing it wrong?

do double-O crosses work better? a lot of it revolves around your target's abilities, i know, but i have had some CLEAR CUT chances go up in smoke for what seems like no reason.

any help out there?
