Having taught archery for many years, I can tell you that draw weight is only ONE of the many things needed for a proper arrow matching. If your daughter is serious and loves the sport (what's not to love?!!) then you will want to equip her with the best possible match for her shooting. There is a vast difference between target/3d arrows and a good hunting arrow. A good hunting arrow has to be tough and you really want a heavier arrow for hunting for kinetic energy transfer. An arrow for target/3d purposes needs to be matched up for straightness against each other (consistency kind of like match grade ammo for a rifle) and can be a much lighter setup for less "rainbow" effect. Since you will probably be wanting lighter, then you will definitely be needing the draw length to calculate total overall arrow length so that you can calculate spine which, with a lighter arrow, will need to be fairly stiff. You also don't want to go TOO light as that will eventually cause damage to her bow. Gold Tip Falcons are usually an excellent choice for the beginning/youth target/3d shooter. They aren't too salty in price but they aren't elcheapos either.
