Chad Hunt is hot.....but the BEST ever in my view was another Chad----Chad Douglas. And my favorite video of his is called Below the Belt.

Yes, Chad Douglas was another of my favs . . . but he didn't do enough work for me to rate him above Chad Hunt. Back in the late 70s, my favourite was ROGER who Roy Dean and others photographed. He only did a few loops for Falcon and others, none particularly brilliant, but he did do the Al Parker 'window cleaner' loop, which is rather good . . .
