What kind of GoldTips are they?
I have heard from credible sources that it is possible to shoot the spine out of them. I have a spine tester that is VERY consistent at work and I haven't seen this with my own though. I have had about 8 dozen over the last 18 months as well, and some of those arrows had well over 10,000 shots on them and still spine, and spin tested fine. I think every arrow I have had that spun and spined well when I first got them were fine after several thousand shots on them.
They were Gold Tip Expeditions and I have no idea how many shots but I culled half of the two dozen I was shooting. They were visibly running out about 1 to 2mm on "The Arrow Inspector". Kinda makes sense that a shaft that is not so straight as the higher end, straighter, more expensive Gold Tips would flex more on impact with the target. Carbon is noted for its memory or its ability to resist a permanent set or go back to its original dimentions but I doubt it can resist forever. Maybe its a lesson on economy of buying better shafts.
