I don’t have a dog in this fight, but st Croix makes as quality a blank as you’ll find anywhere. High modulus rods are super sensitive but intolerant of any level of misuse. This includes overloading, high sticking and rough handling. High sticking is any motion that bends the tip past 90* to the butt, which may not involve pointing the tip vertically. In the OP circumstances I think there was a combination of overload and over flex that contributed. IMO honesty is the best policy. Just tell them what happened and ask respectfully what they can do to help. Good luck.
