keep the hinges clean and well lubricated and you wont have a problem at all. adding the stiffeners to the hood is plain retarded. they were put there to allow the hood to bend in the event of a front impact. adding metal to eliminate this crush point eliminates the bend of the hood, and there's only one place for it to go, straight through the windshield. when it goes through the windshield it carries pretty big potential to decapitate or otherwise severly injure front seat passengers. i like my head too much to bolt those pieces of crap on there, so i'll continue to perform a little bit of preventative maintnance, keep my hood nice and straight, and my head securely attached to my body.
i have seen them in demolition derby trucks climb the windsheild bars or wires, only to find out after further inspection that they were reinforced. we use either 3/8" strap steel, or 6-8 strands of #9 black annealed fence wire run between the dash and the roof, havent had one come through yet, but have had a few try.
