And its sexier!
My company builds two versions of an otherwise functionally equivalent product line, one from aluminum, the other carbon fiber. Folks like to talk about the weight difference, but in our case the real-world differentiator which all recognize but generally goes unmentioned is that the carbon fiber version is cooler and sexier.
I've been scheming for years on ways to build very small diameter / light weight telescopic mic-bar sections out of carbon fiber tubes to replace the repurposed TV telescopic antennas (black steel) used in my rig, mostly because doing so would eliminate folding-mode failure. Its only happened a few times over the course of decade and a half, but on a few occasions I've accidentally fold-kinked a telescopic section tube when hurriedly breaking down at the end of a session, retracting telescopic sections in haste. To continue using the rig prior to replacement of that arm I then need to reinforce the damaged area with a splint made from a split section of rigid plastic tube or a chopstick gaff-taped in place, after-which that section can no longer be fully retracted.
Nesting carbon fiber kite tubes would be perfect, except for the lack of end components that prevent over-extension and provide either sufficient friction (like the current TV antennas) or a locking mechanism sufficient to prevent rotation once deployed, as necessary to maintain the desired orientation of the microphones in the vertical plane.
Might even be able to run small guage coiled wiring internally.
