I'll let you decide between the two.
Aganju is an essential Orisha, essential for growth. he is the foundation of the livelihood of the villages as the volcanic soil helps things to grow.
Ogun is the Orisha of politics, war, iron, black smiths, truth. he removes the obstacles out of your way, takes care of serious problems, protects your prosperity, guards you from harm. Ogun is the great warrior, the great general, who rules iron, metals, tools, weapons, machinery & a very masculine spirit.
I think for this time, I will use Ogun.
