Important Note for ALL strats.

Eh, wasting 10 vultures, what if its against zerg and they go muts?

It is a known fact, that no matter what race you are, ALWAYS build more peons, NEVER stop. Send 1/2 from your last expansion to a new one, over and over, send the ones from depleted mineral fields to scout / to entire new ones.

Yes, vultures are underestimated, but, they are only effective in about 2-3 situations (early game mineral harassment against terran, speed vults to harass toss minerals, and against zerglings)
