Sorry to hear of your get-off Matt. Got my heli ride out of Death Valley about 12 years ago after a 50 mph get-off, getting thrown over the handle bars. Got lobbed 40' from my bike and thought I broke my back as I couldn't get up, but amazingly ended up being just a HUGE stinger with NO broken bones. Nurse in a car that witnessed it was my life-saver. I'm sure the 'ragdoll roll', as you describe it, is what causes bones to break. I didn't have that; just the football throw, landing on my back and fortunately had heavy layers of winter gear on.
Heal up soon, I know those ribs will be the biggest ***** of them all. It's amazing you didn't end up with two collapsed lungs. You're a very lucky man!
