Don't forget, the finer the grind, the tougher the sparge will be.  Larger
pieces promote grainbed development which allows free flowing of sparge water.
  If you mill to a fine flour you will need rice or oat hulls to help avoid a
stuck sparge.  


P.S.  Wheat will promote tannins with too fine a grind.
