Re: Action and Lengths Best For Beginners.
I'd buy her either a 5 or 6 wt Medium to Mediud Fast 9ft Rod & one of The Lines which is 1/2 Size heavier
that way down The Track you won't have to buy another Rod as She will soon get used to it.
There's an Old saying"If you are going to do something properly,it's better to work will The Best Gear,that way you can do it better & quicker ".
Also she would learn quicker with some of her friends if they are into Flyfishing.
Also there's always good Rods for Sale on Places like eBay as well as The Classified Section here.
Incidently a friend has An Allen 9ft #4 or 5 Mythe with a Rio Gold Line,it's a nice setup.
