If you've been breezing through the Arete Tour with nary a second thought, there's hope for you yet. The Defcon arete may be though of as 'Crash Position Direct', a marriage of that route and the highly contemplative Mean Cuisine to it's right.
Boulder up a bit left of the Mean Cuisine start, mincing about on pebbles and edges in the direction of a pair of stingy-looking seams near the arete. Load these up and continue on to an exposed, right-facing corner near the top and a pair of ringbolts.
