Heading down and hiding the genny behind the main in order to furl it does work well. Sometimes if the main is too slack, it furls messily and with more bulk than you want. Then you can feather the boat up and put a little more pressure in the sail, or put some tension on the sheet by hand while you roll it up to get a clean roll.
Also, rolling up while head to wind in a breeze can make the roll so tight that you run out of furling line before the whole sail is in.
