There are a few brands of "carbon" banksticks out there. Just be wary of paying through the nose for those that are just a carbon effect.
I have some of the old Solar carbon sticks, bought for comparatively little when they were sold off. Their demise was brought about because people deemed them not to be real carbon. I haven't a clue what they really are, but they are strong, thin and stupidly light. The added bonus was the carpers, that they were aimed at, didn't really want the long models, or the extensions. Now it's a few years since their demise, second hand prices are easily exceeding the clearance prices.
