I have several set ups, some with 1, some with 3 pots but my goto rig is a somewhat advanced brew in a bag set up, using 1 pot with an insert and a bag inside the insert. I do have a rims set up and recirculate slowly through the whole mash and now Ive added a step. instead of raising the insert up to drain I just leave it in the pot and empty the wort into a bucket or another pot, then I add 6 ph water to the grain and recirculate with that grain bed in place, I do raise the temperature to 170 , then raise the grain to drain and add the first wort back to it leaving me with a 80 to 85 percent efficiency, it seems to work perfect, the only draw back is sometimes I end up with too much wort to boil and have to boil for 120 minutes to reach my target liquid amounts
