If you post in an online forum asking, “I’m new to fly fishing, what rod should I buy first?” there’s a good chance someone will respond with, “Get a 9-foot 5-weight.” You won’t just hear it once. You’ll hear it over and over again.

This isn’t about groupthink. It’s about practicality. More specifically, it’s about what I call “versatility in ignorance.” A 9-foot 5-weight gives new fly anglers the flexibility to explore the sport of fly fishing, without needing to understand every detail.
