I would like to add a few things:
4. Avoid Wyeast smack packs for one gallon batches. They are too much yeast and not resealable. Go with either dry or white labs vials.
Really? White Labs vials and Wyeast contain approximately the same amount of yeast.
Or, did you mean not to use it because, while both Wyeast and White Labs have too much yeast, the White Labs vial can be resealed and the Wyeast pouch cannot.
