I have a Phil's Phalse Bottom in a 5 gallon Rubbermaid and it works great for batch or fly sparge. I tend to fly sparge more because, for me, it's easier and meditative, as I do it by hand, 2 quarts at a time. Dead space is a non-issue as it has a dip-tube of sorts and will suck out almost every drop. I've only had a stuck sparge whenever I tried to drain too fast. Now I just start slow and stay slow. I've never used rice hulls. Another benefit for the plastic is that now that my cooler is all warped up inside I can still get the bottom in and out easily for cleaning. I'm getting around 80% efficiency +- 2% (Brewmasters Warehouse awesome crush). Now if I could just find one for the 10 gallon cooler...

I go about 1 qt/ minute. It takes me about 30 minutes to obtain 6.5 gals with a 1 gallon vorlauf
