i don't nudge, never have, probably never will, but most of my pinhead friends nudge very efficiently. it is part of the game. (they can nudge at my house.)
I have won 1st place in tournaments (pinball wizards Allentown, i think it was 2002 or 2003 without nudging. 2nd place york, i think that same year 2003).
but the question is do you need to nudge?
