I wound up ordering a standard MM3, which is complete overkill for my needs. My standard post-boil kettle volume size is 3.65 to 3.75 gallons. I mill 5 to 8 pounds of malt most of the a time with the occasional 10 to 13 pound 6-gallon batch.
As I stated above, this purchase is more of a want than a need. I already own a fixed-gap Schmidling Malt Mill. I like the look of the 3-roller mill crush. A 3-roller mill definitely leaves more husk material in tact than a 2-roller mill, which a big plus when continuous sparging. Plus, today was the last day to take advantage of NHC show pricing.
