I have been reading a lot of opinions on the common belief that arrow failure somehow has a relationship to arrow spine. For example, there was a thread not long ago that has a fellow with a carbon arrow that had shattered coming off the bow and had a picture of fragments going through his had. It seemed a lot of people believed that the cause of this was an incorrectly spined arrow.


Do you think that a fat, the walled carbon arrow with a spine of maybe 300 resist failure to a thick walled skinny carbon with a 400 spine?

Do you think that a 2512 fat thinned walled aluminum with a spine of .321 be much that tougher and resist failure that better then a 2020 with a .426 spine?

I wonder if there have been any tests done on arrow failure. What do you think?
