The guy - Mr. Longoni? did say they've been on this for decades and that the fibers are unidirectional.My point is its just semantics. In day-to-day lingo 'graphite' and 'carbon-fiber' are often used to describe the exact same material. There are no 'graphite' tubes. Even the older, cheaper ones were are form of carbon-fiber. In Europe CF is often referred to as 'graphite'.
