Comments: Although implied isn't ideal here (>20 is better), throwing some caution to the wind and selling a five wide at the strikes paying at least 10% of the width of the spread in credit. This ends up with me selling the 21 delta and buying the 18, which is a little bit more aggressive than I usually like to go, but selling the 16 and buying the 13 isn't only paying .40, so taking a smidge of more risk here.
