Instead of going to the chains around the corner on the first extension of Illusions, continue straight up over the roof past three more bolts, clip the last bolt of Adios Amigos (A wee bit of rope out for that one) and continue to the anchors. Getting through the roof is the crux. Good route.
Extension of Illusions
4 bolts + Illusions Extension 1, Chain Anchors
