Oakley did a test to see if CF would work on the Gascans. The earstems are made by machining billet carbon fiber like it was done with the C Six. There also exists full builds with CF orbitals as well. Neil Ferrier and Peter Yee joked how it was very, very difficult for Colin Baden to take a pair of the full CF build off since they had so little flex that it got stuck on his head.
