Foot in the foot box, quilt on the side.
But when temps get to where I know its going to be between 60* and 40*, I use the UQ and I sleep in a Swiss Army Fleece Mummy Bag Liner. I tie the draw string to a prusik on the ridgeline to make it easier to get into, climb into it like a regular sleeping bag, and leave it open. If I need to get warmer during the night I just zip it up. Takes a little bit of wriggling to get it right, but so does a TQ.
Anything under 40*, I do that with a top quilt.
