In my experience, the winners are the ones who come with meat cleaver in hand, don't try to cut corners, and take on the full task from the very start, no matter how extensive an effort it may be.
I agree 103% Eric. Don't tip-toe and try to preserve a few links that you think you can sneak by Google. If a link is on the borderline or marginal in value you nuke it. Kill them all with fire the first time. Screw up the courage and rip the bandaid off quickly. Trying to incremental your way out of a penalty like this is a sure fire way to extend your pain.
