Interesting. I've been wondering when carbon would makes its way into a shaft to this level, was curious how it would play. I work in the cycling industry which was transformed by carbon fiber years ago. Not sure I beleive they can sell $600-800 shafts, nor would that price be warranted as carbon is pretty affordable these days, but I could see $400-500 for a carbon shaft maybe. I would love to give one a try sometime, I'm surrounded by carbon fiber engineers, manufacturing, and testing every day so I know how impressive the things you can do with it are. Glad to hear Predator is starting to work with it.
It's not the material cost, it's the fact that Predator currently sells a consumable item. If these shafts were to come out, they would not be able to sell new ones so quickly, so they would lose business and need to price these shafts accordingly.
