Just got my new edge!
The sizing matched up almost perfectly to what the website recommends and the customer service was awesome, I was sort of in between sizes and they emailed me back instantly in which to get. I got the gloss carbon fiber, it's VERY light with super comfy padding and a nice leather chin strap. It's also extremely quiet. I originally got it to mount the contour camera horizontally on the top (as they recommend the EDGE is good for small-format cameras because of the flat top). It does fit, but most of the 'flat/horizontal' mounts I would use are too big for the small flat spot. Besides that, so far so good!
