I am sorry you fell, you are not the only one that sometimes falls while hiking. It usually happens to me every couple of years and I have been averaging about 300 to 500 miles a year on the trails. I nearly broke my nose a couple of years ago but have only had scratches and cuts otherwise. That would have been different if I had a camera strapped to my chest. It would not have done the camera much good either. I meet a lot of people that have never fallen and claim they are careful and never will. But given my track record I both try to avoid any more falls but plan for the worst.I also don't like leaving the camera exposed while hiking; I've fallen and damaged a camera (and a rib) when it was on a shoulder strap on my pack. So I usually keep the camera in a waist bag or holster while hiking.
The HHH is my primary camera bag now, carrying a body and 2-4 lenses along with accessories and filters. I rarely use it on my TT belt however, it's usually on the shoulder strap. I often keep the camera itself out and clipped on my belt or just in my hand with a wrist strap.I love mine on the shoulder strap of my backpack. Makes the camera very convenient to use while hiking and is so much more comfortable, secure, and convenient than chest harnesses and slings when backpacking IMHO.
When not backpacking, I use one on a ThinkTank ProSpeed belt a lot and like that combo very much. I've also got a ThinkTank Hubba Hubba Hiney bag on the belt to hold lenses, filters, and flashes. Wonderful combo.
