First things first, you'll want to infect ONLY Bio Greanadiers (to have the chanse to train a Collosus. If you fail, then at least you'll get a random Archetype zombie). When you're done or if you don't mind missing out on Collosus / Arch.Stalkers, and just want to collect every zed possible, your best bet is to:

Proto level: infect starter Soldiers only


 * Normal* level: infect Armadillos

Advansed level: infect Demolitionists or Peacekeepers, they somehow almost always end up with normal or Adv. zombies

Archetype level: Bio Grenadiers - ~99% rate. Other ~1% is for Collosus which has only one tier.
