I've been researching a lot about rod bamboo rod building before I embark on my own project. When it comes to ferrules, everything I've read so far says that nikle-silver ferrules are THE choice. While I'm sure they are indeed the best, I wonder why no one I've read even considers the possibility of nikle- or chrome-plated brass. They are much more affordable than the nikle-silver ones. Are they poor quality? Should I go ahead and shell out 40$ for nikle-silver, or is it tradition?
