Pardon my ignorance, but what is this "Harold/Creamer Trick"?
Left hand Harold, right hand Creamer. Because of a bug, the Harold does the rocket launcher's damage PER BULLET (double penetrating one shoots 14 bullets) as well as the healing effect (2.5% of all damage you deal is healed). I'm pretty sure the PC has it patched, but it works well on the xbox.
