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.
I too have a spine tester and have been shooting Gold Tips. I wrote down the measurements when I first spine tuned my arrows. I recently tested them again and they were the same. This particular dozen may have been shot only a few thousand times, so maybe this will change down the road. Or, maybe the fact that they are a bit on the stiff side, will lengthen their spine life. I've been curious about this for awhile and will continue to test them down the road.
