There's been much discussion in this forum regarding carbon fiber rods being installed in necks. Besides the weight, tone and stiffness considerations, how would this type of reinforcement do in a rental application? I fix at least half a dozen broken bass and cello necks a week from my rental fleet. I'm curious to know if any of you have found any carbon fiber reinforcement to help the structural integrity of a neck in the event of an accident. Will it help? or just make the repair that much more difficult?
