That being said, I no longer use peat in my mix, however those in my area that do so use the chunkier type and then screen it well before use.

Keep in mind that I live in Micgigan, zone 5/6 and we do not have very dry weather. If I lived in a drier state, my thoughts on using peat may be different, however AAI would still refrain personally from any componate that would take up my air spaces between my other sifted materials.
