Q: “A popular ball cap for years in the Northeast has been one with a long bill. Is there an advantage or disadvantage to such a hat?”
A: For sight-fishing, a long-billed hat is a decided disadvantage. We may not realize it, but when casting, we monitor the fly line as it unrolls to the target. A standard baseball-cap brim allows you to see the line throughout its flight. A long bill does not.
