I have sent rod back the St. Croix about 5 times now. That reminds me, I have three more to go back soon. Send the stick, a written description of the problem, and $15 to St. Croix. They will take care of you. A lengthwise split in the blank sounds a like a manufacturing flaw to me. I have broken more rods than most people will ever own, and the only thing close to that I have seen resulted from crushing the blank, but that results in more than one crack.
