Thanks for the ideas and comments fellas! With y'alls help, I'm sure we can get him fixed up. Ryan, I tried the really light longbow with 1/4" dowell arrows. . He just doesn't have enough use of the arm to make it work unassisted. When I get the bracer figured out it will likely be using a bow like that though.
Sleek, that's a possibility. I want to try and keep his shooting form as close to normal as possible, but if that doesn't work we might explore that option or the teeth draw. Although, since he just got braces his Mom might not want to risk messing up all the dentists expensive work. Thanks again fellas! Josh
