Im definately a function over form guy, and usually i dont care if you like how it looks as long as it offers a performance advantage, such as being light weight. But i have had a stock hood come up at interstate speeds while riding in a friends car, who somehow didnt know his latch was broken. Its a very interesting experience to have a hood fly into the windshield while driving, and stay there. A CF hood that waves at interstate speeds always makes me wonder when its coming up ( i rarely drive at "normal" interstate speeds) and that weight reduction gained by running that cf hood isnt worth the repairs needed when it comes off. Id rather run a 12 pound aluminum hood that doesnt wave at 100mph+ than a 5 pound cf hood that waves at 85. But thats just me.... and i seriously have an issue with CF ever since it became a fad. but to each there own, as long as everyones staying safe there shouldnt be any serious concerns.
