What if you were metalborn

Let's say a mist comes over every night for 16 nights and then once a week for 16 weeks during the day. Anyone who touches the mist has a chance to become a metalborn

1/16 chance you become metalborn

If you become metalborn it's even odds you're a feruchemist or allomancer but 1/16 of the people who become metalborn will be mistborn or a full feruchemist

In this hypothetical do you go out into the mist and take a chance or do you take a deal right now to become either a misting or ferring of the metal of your choice (not twinborn)

If you pick to choose your ability what are you picking and what are you doing with your ability.
