Metal, I like you, you are consistently entertaining, and perhaps most importantly you are a ball breaker, but you are not quite right on this. A heavy steel frame may well be stronger than the average CF frame. But that is because CF is used more often on the high end stuff at his point. Lightweight steel is a delicate beast. Any light weight frame gives up some longevity by it's very nature. Comparing the strength of a Surly to a carbon frame that weighs under a Kg is apples to oranges. Comparing that CF frame to one of those Rodriguez frames would be more appropriate. I can assure you, that no one owning one of those super thin walled steel race bikes is being casual about letting it drop.
