Many hot n fast people use butcher paper, not foil!
A thought on the probing and hot n fast. When cooking hot n fast, it generally takes a higher finishing temp to reach the "probe like butter" feel. So it may not have been quite done yet at 201. And if it didn't probe good at 190, or fall apart at 201, then it was not overcooked. Overcooked flats will fall apart when slicing.
