If you wanna go big:
Cover your face COMPLETELY (ski mask). Have a vehicle outside of camera range ready to go. Having a strap is preferable, but you don't necessarily need one. Go into a bank with generally low customer traffic. Audibly state that you will kill anyone that pulls an alarm (bank employees are taught to only pull when they are safe). This is where having an accomplice will help- they can watch the platform/banker side and make sure they aren't doing anything stupid. Audibly state that you want both the top and bottom drawers of each register, WITHOUT BAIT (aka trackers and dye). Employees are taught to follow all commands and to be safe, so it's important that you vocalize this. Have them let you behind the drawer. Don't worry about an employee testing you - they wont. First collect all register drawers. Then have them open the vault drawers (usually will take several people depending on the bank and how they are assigned.) They should be leaving a small stack of bait bills in the drawer/vault. Don't take every last bill. Again, emphasize NO TRACKERS. Collect it all and leave immediately. This shouldn't take more than 5-10 minutes.
You can clear around 250k+ from a typical bank doing this. People get away with it all the time.
edit: casing the layout of the bank beforehand helps as well, obviously
on the low
there hasnt been a year that feds caught more bank robbers than those that got away
Jackson, MS and Baton Rouge, LA
are the 2 best areas in the US to rob

a bank and get away
those 2 cities are ALWAYS in the to 10 as far as bank robberies and offenders who got away
A VERY LARGE % OF THOSE CASES DID NOT MAKE THE NEWS AT ALL
I personally know of some deeds
and seriously had thoughts of doing this while in college
there were certain banks in Jackson that got rob so much that that branch was closed
