The cause of missing inserts is at least partially due to handling. Reeling weights into the tip, poking snags free, rod lockers, bumps, bangs, crushes etc. 💯 nothing to do with braid. Yes some higher quality guides take more abuse before showing signs but none are immune. The only fix is replacement of the guide. Tips are easier, both can be diy if you’re handy and not overly concerned with cosmetics. A professional repair won’t break the bank either.
