Never assume that just because a rod is rated by the company as a ten or twelve or whatever weight that it is "strong". I'm attaching a picture of a fine little lady (103 pounds) that broke a 14 weight rod on 25 pound Jack. She was trying to bring the fish close enough to gaff, and whoops, a broken rod. Notice the tip section hanging by the fish. The rod had that same day landed several other Jacks and a few smallish tarpon. As far as we know there were no scrapes or nicks on the shaft of the rod that led to its failure. The back-up rod of the same weight and manufacturer also failed, but on a 70pound tarpon, under the same conditions, trying to bring it to the side of the boat.
I know you all want to know the manufacturer.....TFO. After cooresponding with them about the failures, they assured me that they have addressed the issue on the newer rods. The failures occured two years ago.
