And to answer your question, I have only ever used shop bought rods. I would love some custom made, but no one building using the blank I wanted, for a price I could afford! (Trebuchet light)
For me, I went for a mass produced rod, from a company, and shop, that I knew of it snapped on the first outing, I could have it replaced quickly and easily. Rod blanks can have slight imperfections, and even the best rods can snap. And for me, i like the comfort in the back of my mind that if it breaks due to a manufacturing error, it won't be a hastle, with 6months wait for a replacement.
