Which Zelgius?

So, April orbs proved to be really lucky and now I have the first world problem of having 3x Zelgius, all with good IVs. I have +atk/- def, + spd/-res, +def/-HP. I know I know, I'm a lucky bastard. I'm leaning towards +atk/-def because I want a hybrid tank who can fight Grima and I have access to a bold fighter which I feel pairs best with +atk. Any input is appreciated.
