I would ask the summoner's player how s/he intends to use the eidolon. That piece of information may give you the final push in terms of deciding what role needs more support. An eidolon will never be a real tank, lagging behind in hitpoints compared to a barbar or even a fighter, but with a few spells its AC can get rather silly.

The summoner told me he wants to create a Leviathan from the FF type creature, athough he cannot give it the Tsunami spell maybe he can add lightning bolt. Now that I know that I'm thinking I should take the tank role in the group, so I believe Sea Reaver will be a best fit. One thing that I have thought I might change is changing is species, how about a Catfolk Sea Reaver?
