So my father in law purchased a bear fortus x bow a few years ago and it’s time for new bolts. The current trophy ridge x ray bolts are 20” and 10.7 gpi with a 125gr field point. The issue is I can’t find anything similar in weight and I can’t find any information on spine. Bear says 370gr minimum total arrow weight with no max weight. How much of an issue is spine in a x bow? Any bolts that are stiffer than others. The information I’ve found from manufacturers seems to be pretty thin. I know there are some knowledgeable x bow shooters on here so hopefully you can help me out.
