There are three main variables to consider when choosing a fly rod:

Rod Weight Wt. 1-3: Smaller Trout... panfish and other small species. Wt. 4: Panfish and small to sized trout. Wt. 5-6: Medium trout and smaller bass. Wt. 7-8: Salmon, Steelhead, large trout, large bass. Wt. 9-14: Large salmon, Tarpon and other large saltwater species.

Rod Action: Fast, Medium and Slow are the three main classification used to describe a fly rod's action. Fast Action - Most of the rod is stiff except near the tip. Slow Action - These rods are very flexible. Medium Action - Moderately flexible and probably the most versatile kind of action.

Rod Length: The most common rod lengths are between 8-10 foot. Shorter rods are better for short casts and where the surrounding enviroment would make casting a longer rod difficult (like being closely surrounded by trees and brush), while a longer rod generally allows for a longer cast .
