1. Fly Line Weight - The weight of a fly line should be same as weight of your fly rod and fly reel. Using wrong weight fly line will unbalance a fly rod, leading to poor casting and long days on water.

2. Fly Line Taper - The taper of a fly line refers to enhancements made to fly line to provide better casting. The most popular taper is weight-forward taper, which is ideal fly line for beginner. The weight forward taper fly line is also most versatile line available.

3. Fly Line Density - The density of a fly line refers to whether line sinks or not. A floating fly line should always be first line used by beginners as it is most versatile as well as easiest to cast. Other fly lines that sink all have their uses, though, so more experienced anglers - especially those that fish in lakes, saltwater or subsurface with nymphs, should also pick up a sinking fly line that meets their fishing needs.

4. Fly Line Color - For top water fly fishing, get a fly line that is easy for you to see in all fishing conditions.

Fly Lines for Fly Fishing

0 – 2 weight: For ultra-light freaks. Designed to handle smallest flies in smallest waters and making most delicate of presentations. A short 1 wt rod and a 1 wt floating line will make that 6-incher feel like a whale. Casting range = 30 feet.

3 – 4 weight: Also for fishing small flies and making delicate presentations. These are very common for stream fishermen and also very effective. Not overkill for small stream trout, able to handle larger trout and ideal for some of smaller warm-water species. Casting range = 30 – 60 feet.
