I have a level 6 Lunar Oracle with eldritch heratige (arcane) in a home RotRL campaign. Come level 7, I intend to take improved familiar and get a small elemental with the valet archetype from Animal Archive. I'm having trouble deciding between the air and lightning elementals; my question is which would be a better choice and why?

Almost definitely the air elemental. The lightning elemental has some offensive power the air elemental lacks, but this simply isn't enough to make a difference in the scheme of things. The air elemental has whirlwind and is also a good deal more durable than the lightning elemental
Reading through whirlwind, it looks like it'll only affect tiny or smaller creatures. On the other hand, while less durable, the lightning elemental gets +15 to CMB on a charge against metal bearing opponents.
Well from a roleplaying standpoint (based on the little information I have) I really wouldn't understand why a lunar oracle would get a lightning elemental as a familiar. even air seems slightly more appropriate. (although not that much)
His whole deal is that he's a kind of conduit for nature spirits. He's got the haunted curse and a totem guide archetype wolf animal companion. The elemental improved familiar would basically be his existing raven familiar transforming into a more primal nature spirit form.
