Middle name help for Nathaniel!

Hi everyone! My husband and I are having the HARDEST time choosing a name for our baby boy. We have finally decided on Nathaniel (Nate) for the first name, but need help with the middle name. Some of our favorites are:
Nathaniel Vale
Nathaniel Oak
Nathaniel Brooks
Nathaniel Tate
Nathaniel Bray
Nathaniel Sloan
Which do you guys like best? Any other suggestions for short unique/trendy middle names?
