RE: Is arrow spine (deflection) the only attribute associated with arrow failure
I do agree that the spine was most likely not the reason that the persons arrow exploded on release BUT arrows are becoming more and more dangerous these days with the extremely thin walled shafts that are out there.Some of the fat shaft carbons are just plain scary how thin the wall thickness is.This will definately cause an arrow to fatigue quicker and damage easier,resulting in exploding arrows.Even aluminum arrows are subject to this but not as likely.
