Jewelry is pretty simple, it's always one small thing that goes wrong. Nightclub isn't very hard either to stealth you just need everything to go right and good communication.

I can honestly say I've never stealthed a bank run before though. Seems like it'd be very hard with only the beta talent tree, we'll probably seeing a lot more stealth runs of banks when the level cap is higher. I'm not too sure what the max level cap (i think 100) will be but there's 120 skill points iirc.
