I have an awesome friend who just bought me a brand new Contour+2 with a bunch of mounts. I have had really good luck filming my sessions using the Camrig Strut Mount with the GoPro Hero2 for about 6 months now. My GoPro fancy-shmancy dive housing decided that it wouldn't keep the water out. So, no more GoPro. After all of the problems I had with my GoPro and the pretty terrible customer support they gave me, I decided to go with the Contour. Yeah, not as good as the Hero3 Black as far as frame-rate and all that, but I am no Michael Bay. I can hardly tell the difference.
I put this together tonight: I took the flex strap mount and tossed the rubber strap it came with in the drawer (too short). I picked up a set of 7/8" wide Velcro One-Wrap straps at Home Depot for about $5. I punched a small oval at either end of the strap and made a very secure wrap to go around the center strut. I may be mistaken, but I think that the Camrig strut mount uses the same stuff, but a bit narrower. It fits super tight, and the little rubber pad on the back of the swivel mount keeps it in place nicely.
What do you all think of this? I hope to try it out if the winds will cooperate soon. I am going to dummy-cord it to the strut in case of something catastrophic, but I don't think that it can go anywhere. The center strut on my Switch Element tapers toward the tip. So, by mounting it about a foot from the leading edge (where the canopy joins the strut) it cannot slide down closer to the leading edge -- it is locked in place. There is even enough room on the T-rail to mount a second flex strap! Not sure if that is necessary. I figure that I will start with one strap and see if the camera moves around too much. It feels every bit as solid as the Camrig Strut Mount for the GoPro though.
