Frequently Asked Questions (FAQs)

1. Can you use normal line for fly fishing?

1. Assemble Your Leader-Making Materials and Tools. You'll need a few varieties of line in several sizes to build the different sections of the leader. You can use either mono or fluorocarbon, but to keep things simple, our recommendations will focus on nylon monofilament.

2. What color fly line is best for trout?

Fly lines with monofilament cores can have a clear coating. “Clear” may seem to be the best color in terms of not spooking fish, but an all-clear line serves little purpose since in most cases the trout only sees your leader.

3. What is the easiest fly line to cast?

The Level Taper (L) fly line is the easiest of all fly line tapers to grasp simply because it has no taper. A level taper fly line has the exact same width and weight throughout it's entire length.
