So she is pulling a bit under 25#. It is more a question of bow weight than bow length, so maybe you have a 45# bow that she could work into?
If she is kinda iffy on shooting to begin with, she may not want to put that much effort into "weight training", but a 45 pounder would be about 33# at her draw, depending on design. Maybe you can find a used Kodiak Magnum (I know...I push these a lot, but they are a great bow.) that weights between 40 and 45. They made a lot of them in the late sixties and early seventies that were in a greater variety of weights, not your standard 45, 55, 55, etc..
Or you could just go ahead and order her a custom ACS. :rolleyes:
Killdeer :D
