I mainly use cam 9, 10, 8 to avoid some phantom animatronics. Keep stalling Springtrap in cam 9 or 10, but I prefer cam 9 more than cam 10 because in cam 9 he might go to cam 10 stalling himself. Keep cam 14(vent) sealed, if there's vent sound, check cam 11 to see if he is there or not and seal it if so, if not, try to lure him back to cam 9 or 8 if he exits the vent and try to keep cam 14 sealed again. If I cannot find him, I will lure to cam 5 or 8 first then back to lure in cam 9 again.
