Braid doesn't break rods, fishermen do.
And how would they know unless you're compulsively honest enough to tell them? Unspool the reel before you send it back, DU-UH
"Some monster fish just smoked it. Stopped her, turned her, the reel started making funky noises and she made another run and emptied the spool----nuttin' I could do"
I doubt they could tell from examining the fracture that a rod was used with braid.
