Carbon Fiber would be cool but real CF tube would be big $$$$. I'll check around and see what it really goes for.
A CF overlay could be done reasonable though, I have some left over from a console I built for my BMW.... My bug has no CF so I probably won't be going that way. It will eventually get a CF roof lip but it may end up painted with the body.
I'll be working on this column project over the next couple of weeks, I'll take pics, submit a tech article and post them on my website when it's done. Check out
www.e21motorsports.com/kendanielson my Bug project is on there, a page on header design and be sure to check out my '82 BMW 320is if you are interested in programable EFI. That little sucker really rocks now with efi and an new 4-2-1 header and exhaust system!! EDIS is comming soon. The EFI and EDIS will find it's way onto my type 4 in the future..... VERY cool stuff!

OK, I just found some 2" id carbon fiber tubing used for sailboat spiniker poles-$50 per ft.!!! So there's an extra $90 or so over the other materials for little gain, it's .35 lb per ft and 4130 chromemolly is about .40lb per ft. No bang for the $ there just cool factor.
