You know Patm the more I think about it Laubin made some 52" bows that pulled 65lb @26" he believed quality osage was as good as horn in compression, Im not saying I beleve it but this stave is one of the best I have ever seen no knots beutiful rings so Im going to take this one to at least 29" @45lb or if need be drop the weight some, I think it will take it ,Im using elk sinew and letting it cure at least 4 months or better , I will post more when tillered to 20" & brace just got it to long string !
