[QUOTE="yankster, post: 718170, member: 4171"] I guess I'm still trying to wrap my head around it all. All the talk of testing body movement seems to refer to high speed crashes during desert racing factoring in front collision and side to side movement in a rollover, and not the hard hit from the bottom like casing on a jump or landing skid-plate-first on a rock from a 20 foot drop. Makes me think of the science project in school trying to drop an egg from two stories up without it breaking. The only kid who passed that test hollowed out a Nerf football and put the egg inside, thus securing it against any movement that wasn't countered by foam. Reducing that foam layer to 1/2" would have shattered the lightweight egg on impact so I'm trying to understand how a thin layer of high density foam can save a 200 pound man's spine from a drop on a rock. Not saying it wouldn't by the way, just asking the question. [/QUOTE]
