A while back I was experimenting with the reflector by bouncing back light into the shot from two hair lights behind the model pointed towards the camera. I had the reflector on a stand and I was literally holding the camera up in front of it so that the viewfinder was pressed against it and taking pictures using the blessings of autofocus alone because I couldn't look through the lens. It then dawned on me 'to hell with this' and I cut a very rudimentary hole in the middle of my reflector so I could see what was actually going on. From there I ended up changing the lights around by putting a big softbox behind the model and letting my reflector simultaneously be the key-light and the fill-light.
