If you plan on buying one I would go to
www.basspro.com they have different name brands and they have many bows that range from 40 pounds and up and I am planning on buying the Martin Jaguar Magnum compound bow that is between 55-70 pounds and they also have it between 35-50 pounds, I would check out the website I gave you. Hope I helped in some way and i am 13 so I had ran into the problem of the bow length because I have a 26 inch draw length and thats were I shop for my bows.
