Thanks everyone....love the group here how everyone is so supportive!
For those wondering about the camera and mounting system, it's a Contour Camera that records in high def. I got a 16G micro card for it so can record the whole season on a card and still have space. I like the shape of it and how it mounts to stuff vs. the GoPro model.
I made a plate on top of my armguard to mount one of the mounting discs that the camera snaps into. I also have a headstrap but can't see the buttons to operate the camera when it's on my head. The footage from the headstrap is good but you need to mount it so the camera points out to the left (rt. handed shooter) so that when you turn to shoot that the target is in view. You also have to remember to hold your head turned to follow the animal in as the camera is pointed out to the side.
For these reasons I went with the arm mount even though there is "shock" at the shot. Also gives a nice "down the arrow" view.
Here's a pic of the plate with mounting disc I rigged minus the camera.
