Possible Names for my heist movie

Below is a list of possible names for my heist movie, with reasons why I think they maybe suitable.

I have one or two favourites but as part of my primary research i'm going to discuss the outline of my story and the genre with a focus group before asking them to rate each title out of 10. This will help me pick the most appropriate title for my film.

ART THIEVES: Very direct and to the point, mentions the plot of the movie indicating that the heists will be of galleries and museums.

ROBBERY: Also direct and indicates genre, however keeps some mystery as to what the targets will be.

THE LAST JOB: Indicates the size of the robbery (it must be big as it's their last heist) and puts added pressure on the job as they will be retiring from crime after.

SEVEN DAYS: Focuses on the length of the robbery/robberies giving an idea of the scale - links to the tagline.

STING: This is another way of saying that someone gets duped/robbed. I'm not sure that a modern audience will understand the meaning of the word.

THE SMOOTH STING: Similar to above, but the suggestion is that the heists should run smoothly. The problems with the name are the same as above.

THE MARK: This is a term used within the genre for the person/company that is getting robbed.

MASTER THIEVES: Indicates how experienced the crew are.

THE TARGET: All robberies have a target. This title doesn't reveal exactly what is being robbed, so creates mystery.

THE MUSEUM HEIST: Indicates clearly exactly what is going to be robbed. It's probably a bit too direct.
