I'm in the process of mounting a PC101 to the side of my Gath. I also use mine only for fun at this time. I love the Gath because of it's narrow profile to keep it away from your riser. At first I was using a Velocity. Way too wide, so the camera would be pressed against my riser. I'll let you know in a couple of weeks how it goes, or if my camera breaks off at 10000 ft.
