Quick balls are useless in raids. You cannot use it at the start of the first turn, which is when quick balls are efficient. Also, the only Dynamax Pokemon with ??? Weight are Gigantamax Pokemon. Therefore, if you threw a heavy ball at a Snorlax in a max raid battle, it would be just as effective as outside of a raid den. Remember, if it's your raid, and it's not promoted, you have a 100% chance to catch whatever Pokemon you're against.
