I could have sworn I've seen this discussed, but I couldn't find the thread, so I thought I'd ask again. Would it be wiser to use two truss rods in a six string neck over one with two graphite rods? I was thinking I would put in one truss rod and two graphite reinforcement bars, but then I got to thinking- that's a fairly wide neck. What if it starts to twist? Then again, if the neck is built well and has the graphite bars, maybe it shouldn't need the second truss rod. What are your thoughts on the matter?
