I'll have my own grain mill in the very near future, but I'll try Jeff's or Billy's mills if I brew again before getting my own.
Hmmm... Ok. I'll try that. When I first went through all that gear you delivered, I was trying to figure out what that was for. It seemed too clean (pristine white with no husk or anything stuck to/in it) to have ever been in contact with grain, so I thought it just went above the grain. It's got a center hole cut in it with foam that can optionally be removed, and I thought that the sparge sprinkler went through this hole... or... sparge water was trickled on top of the foam to disperse it better.
Now that I know wtf it is, I'll use it next time.
