I've only used steel, so I'm curious about the others. I looked up a few carbon fiber users on the internet. Some lov'em other say there's not much weight savings to made a difference, they cost much more and damage more easily than even aluminum. (really)?
Carbon fiber just looks and sounds cool. lol....
(maybe ain't worth a crap, I don't know)
Or, with as short as the shaft is in our Cobra's, don't matter anyhow pa.
What do you have and why ?
