Triple the number of pitons. You might need four or even six times the number of beaks and blades listed on the first-time nailing rack. Get specialized gear. Pare down your lead rack so you only carry enough for 30 feet or so at a stretch. Leave the rest of the rack at the belay, and haul it up as needed.
Hard aid is mostly mental.
Don't worry about time or efficiency. Better to make many short placements and stay low in your aiders than overreach, lever out on a piece, and pop it. Pay closer attention to bounce testing. Stay low and bounce test aggressively. If each placement in the chain gets tested to over bodyweight, you can securely string together long, dubious aid passages.
