I like the weight loss properties as much as the next guy but I've heard of instances in which they have failed. Of course there is the extra added bonus of safety with CF shafts as they won't pole vault your vehicle like your typical 1pc. And just for the record, I did do my share of research on it Kenny. I just never found anything significant to make CF the end all beat all. So......*shrug*.....I like the aluminum ones.
