You've picked a great time. Women are now flocking to the flyfishing arena. The advent of graphite rods cut the weight of a typical outfit in half, and since then flyfishing has left the realm of aficiando and started catering to the masses. It isn't necessary to practice for frustrating weeks now to throw a decent loop 60 feet. With proper lessons, a novice angler can be effectively working a river in a matter of days.
Today there is a wide variety of equipment specifically tailored for women.
This brings up an excellent point about rods. For the female gender, the lighter the rod, the better. Let's face it, men have stronger wrists and larger hands than women, which allows them to control larger, heavier rods for longer periods of time. Women once had to learn to compensate for this, but they no longer have to. A cast of 50 feet, plenty of distance for most angling situations, can be achieved with finesse and good timing.
