I've been shooting the Cabela's camo carbons(made by black hawk)The specs. say +or- .003 straightness and +or- 3grs. weight variation per doz. To get those same specs. in other brands you'll pay more than the $69.00 per doz. that Cabela's charges.I've been very pleased with them,and don't hesitate to suggest them to anyone looking to try carbons.
