I haven't used a conical, but am interested. I see one possible advantage of the Malt Mechanics. The MM has a bottom tap. No more whirlpooling or filtering wort going into the fermenter. Dump, let trub settle, drain out the bottom, pitch. Has anyone done this? Both the MM and the BB have a tap a little ways up, for draining beer off from sediment at the end of fermentation.
