Just a comment on weight and inertia effects.
When Dale Earnhardt hit the wall at Daytona his car frame absorbed a lot of the impact but his head with a heavy helmet was not restrained. So at the 15G impact force, his head and helmet was over 1 ton at 180 MPH to 0 MPH. It fractured his skull and snapped his neck at the Atlas and Axis. They say he was dead before the car stopped.

Fast forward to me in my 2015 crash when I hit the concrete barrier at just 75 MPH. The impact moved my head forward and I had a sharp stab of pain in my head and blacked out for a split second. When xrays were done I had fractured my C4, C5 and C6 vertebra but no damage was seen to my spinal cord. But we later found out there was damage.
My helmet then was a Vega Summit II and it was 5.13 pounds.
My current G Max 54S is 4.34 pounds.
WSPollack's Noland N-90 and N-100-5 weigh 3.8 pounds.
Choose wisely.
Dress for the crash, not for how your friends see you.
