So this is my 3rd playthrough and second Sniper/ NCR character. At the moment I am Neutral to all factions (Except Powder Gangers) and I'm wondering when is the best opportunity to break it and start wiping out CL and kill House? Right now I just got the mission from Caesar to destroy the bunker.. what should I do?

1. Kill Caesar, Enter the bunker, destroy it.

2. Kill Caesar, take the chip to the bunker, Lie to House, Disable all the robots, then leave completing two of Houses missions.

3. Leave Caesar, Enter the bunker, destroy it (Will this give me positive CL karma? I don't want that)

4. Leave Caesar, Ignore the Bunker, Go kill House (Problem is I want to get all the Snowglobes first, how long does this take?)

5. Leave Caesar, Ignore the bunker, Ignore House, wait till I have to make a decision (When do I have to choose between NCR and CL?)

6. Leave Caesar, Disable the Robots, enter bunker to complete the missions, Ignore House (Does disabling them turn him hostile?) till I have to kill him. <--- My First Choice if hes not hostile upon disabling the robots.

Basically I don't want to miss anything that I can't get if I'm vilified with CL or if I kill House.. Namely the Snowglobes.. Anyway, what should I do?
