Vacillate
verb/vas-uh-late/
alternate or waver between different opinions or actions; be indecisive.
In contextI tend to vacillate between choices when faced with a diverse menu.
Remember it
Sounds like 'oscillate' — a vacillating mind swings back and forth and can't settle.
Use it well
Use 'vacillate between X and Y' for indecision; more formal than 'chop and change'.
