I've owned the Cinch version 1 for over a year and when I use a strap it's the only one I'll choose - it's been amazing. From toting around a 70-200 2.8 + 2x teleconverter all day long during the Head of the Hooch Regatta to just a 10.5 fisheye while touring the VAB at Kennedy Space Center it's kept the camera close and easy to access. I love it's simplicity, the machined bits, and how fast it adjusts.
When Greg and Duncan announced version 2, I knew I had to get it. After a few weeks of anxious waiting, I got it. I've been using it for a month or so now, here is what I think so far.
