Just some observations:
I've been pondering your crash as well as my little spill.... the difference being you were at speed, I wasn't.
It seems if one has a tip-over like mine, the major injury is to the hip area (not including any strains) & possibly the hands/wrists.
In a moving crash, it's anyone's guess... highside, lowside, head-on, etc. A lot of variables come into play including road surface, road surroundings, obstacles, ATTGATT, speed, etc.
Helmets come into play at some point, of course. I like my full-face Bell because it's very lightweight, however I also like my Nolan 102 because of the convenience, even though it's much heavier.
Besides the 'standard' ATGATT, here's what I do to help reduce the off-chance injury.
1. Tight fitting helmet (no matter what type). Very little if no side to side play.
2. Cuffed gloves. After looking at Greg's coat sleeve, I think that part of the injury might have been prevented by full-cuffed gloves. My gloves cover 4-6 inches up my wrist & sleeve, making it very hard for the coat sleeve to slip out & up.
3. Even though all my pants as well as my full leather suit has hip pads, they are very thin (nearly useless). I have added the extra minute or so to put on my Bohn armored long pants (without the ship pads) or the Bohn armored shorts (the blue ones). I know if I had been wearing the Bohn stuff when I went down, I would not be limping around with a bruised hip bone.
