I am never sure what will come up during my journey as a rod builder. A lot of repairs come through the door and are usually handled quite easily. I got a bamboo rod in for a new ferrule a while ago and had to learn an entirely new language.
After my online education, I was able to speak correctly and know what part I needed.
Bamboo rods should appeal to me because of my background in jewelry and furniture. I have tried several and the biggest attribute they possess is their nostalgia. Modern materials, fiberglass, and carbon fiber have more of what we look for in a rod. Purists may scoff, but everybody has their opinion.
