No downhaul and let her rotate on its own to get good flow around the main with the wind mast. Remember the (nearly) centered and firm mainsail is also the backstay and you have the diamonds supporting most of the mast's lateral axis which is enough to support the chute with a rotated mast.

BTW, it is not a pretty sight if you forget the downhaul and there is a good wind. The pull from the chute and the downhaul induces a reverse mast bend. Yikes.
