Question "why does my rod keep breaking in the same spot."
Why did my rod break? Why do I keep breaking in the same spot?
We can’t recommend this article enough! It is a very thorough look at how graphite failures happen with fishing rods:
Rod Failure by Tom Kirkman
Graphite fly rods can withstand a lot of stress and survive. They can even take the occasional nick or impact. All rods do have a limit to how much bend they can survive before breaking.
By far, the most common breakage issue we see is from “high sticking.” This is when you stick the rod straight up, and maybe even a bit back with the fish or other heavy object directly below you, causing significant stress near the ferrules in the top sections. This will break just about any rod of any weight. Always apply pressure off to your side when doing any significant pulling. Leave the “rod up in the air” stuff to the TV guys.
The next most common breakage issue we see with graphite rods are spots on the rods that are weakened by being hit with a fast moving object; usually split shot weights or a weighted fly. This is common with certain nymphing techniques to hit the rod blank in the same spot with split shot several times over. If you have a rod that is breaking in the same spot more than once, pay close attention to your casting technique. You may not always notice the impact happening
