About the Kadova hoops sticking, a friend of mine uses them and says she makes sure the hoops are the same temp as the curds when filling. She either dips them into the warm whey or warm vinegar water mix at the same temp as curds. Too much psi though and no matter what they will stick. I usually flip the cheese in the hoops more often than most to make sure they aren't on their way to sticking. Works for me.
