I am an Osage guy, and I think it's hard to beat whether one is a newbie or a journeyman but, any of the well known bow woods will work. Elm, Ash, Hickory, Pecan, Hackberry, Hard Maple, and many others. Start with a good straight stave with as few blemishes as possible. Make sure it was cared for properly and it is dry. From there design and execution will get you just about anything you want. Design and execution being at the top of the list before wood choice.
