If you are looking for a starter pack, this thread should help out nicely:
If you are sensitive to colognes - Ammo’s FF21 scent is the one that gets me. I can tolerate it for a few hours but start getting problems after that. Any idea how you get on with cool water? That triggers more or less the same irritation for me, so if you don’t get problems, fine. 
However Ammo can be custom ordered in any other AD scent and the Summer Ammo scent is a very different matter - No problems at all.
I’ve never had a problem with any of the other AD scents - Neroli, Akuto or Grapefruit. All the Instants come in Neroli and A314 is in Akuto.
