When I used to fly sparge I prefered a false bottom, for the same reason sause said. But now, I prefer a batch sparge and a bazooka tube while I circulate the herms. This gets my effeciency up pretty good, and increases my starch conversion times. I rely more on a sparge ring to prevent channeling, then a bazooka tube or false bottom this way.
Why yes, yes I am a metrosexual!
