if you are serious - i am glad to help you.... and anyone else who might be interested... .
i usually start girls from teenagers close to adult size - up to young adults - who have never shot a bow before... and might be slight of build.. with a PSE Snake... ..it;s the same bow jennifer lawrence used when she played katness in hunger games... except hers was painted silver.... ... .it;s fiberglass and ambidextrious - meaning it has an arrow shelf on both sides.... relatively inexpensive.... and draws 25 pounds at 28 inches - which is the average draw length of most people.... . and 25 pounds is an easy weight to manage not likely to cause injury... ....
3 rivers archery has a good youth arrow that is 28 inches long and can handle being shot from bows with peak draw weights from 20 pounds to 35 pounds.... . it;s about as heavy an arrow as i would shoot from that bow.. .and it;s put together already....but i use lighter weight eastman aluminum arrows in the 1800 to 1900 range that i fletch with feathers for the stronger archers i start on this bow.... .and arrows i make myself of 1/4 birch for those younger and smaller archers with shorter draw lengths... ..
for girls with more muscle and more athletic build i use the same bow i start boys from teenagers on with... .a bear titan.. .. it;s the same bow most highschools use for their archery instruction classes... . 30 pound draw weight at 28 inches... also ambidextrious and virtually indestructable..... same 3 rivers wooden arrows will work for this one but it will also shoot slightly heavier arrows spined for 30 to 35 pounds well.... .aluminum and lightweight carbon or fiberglass arrows made for bows of 30 to 35 pounds.... if someone can pull the full draw length on this bow and maybe a little further i have them use beman hunter junior arrows.. ..re-fletched with feathers.... they;re good for bows up to 40 pounds..... . ...
for a traditional bow it;s important to have the arrows fletched with feathers not plastic vanes.... the plastic fletching is made for compound bows mostly and tend to throw the arrow off when shot from traditional bows... ...... feathers give way when the arrow crosses shelf or bow hand then expand back again....
also it;s important to have field points on any arrow used at a range or for training... . never let a new archer attempt to use broadheads ... . they are banned at most archery ranges anyway..... but even using them in private just for practice has had a history of disastrous and even tragic results.... . they are made for hunting only and for experienced archers..... .....
in addition to a bow and good arrows she will also need an arm guard for the bow arm and a shooting glove to protect fingers that grip the bow string.... .i don;t let students shoot without those 2 things.... especially young ones.. ....painful bruises on the inner forearm and blistered fingers or fingernails ripped off can ruin enthusiasm for archery quickly.......
and she will need some kind of quiver or arrow bag to keep arrows in or contain them until ready to shoot..... all kinds of quivers are out there from the ground kind that are free standing to back quivers and side quivers..... you can even make an arrow stand out of pvc pipe if you wanted to......
